Hey guys chris fix here and today, i'm going to show you how to safely and properly replace a broken rear, windshield and the best part is whether you're replacing the front windshield or the rear windshield. The main steps to do it are very similar for most makes and models, so i'm gon na break down those steps very clearly and easily in this video. So after you're done watching the video you'll be able to tackle a job just like this now you're, probably asking yourself: how does something like this happen? Well, let me show you my dad was just getting in the car, like any normal person, he's going to go. Use it so he gets in like this.

He goes to close the door like this and the rear windshield explodes it blows out and shatters all over the place very unexpectedly, good thing. Nobody was back there now, unlike the front windshield, which is a laminated windshield. The rear windshield is made of tempered glass, so these only break for two reasons. The first reason is the vents in the car are clogged.

So when you close the door, it creates a lot of pressure and that pressure buildup causes it to blow out so i'll. Show you how to check that real, quick and the second reason is this car is parked in the street a lot people mow their lawns. People drive by if a rock or something hard and sharp kicks up and lands on the glass. If it's pointy it'll break the glass.

What real, quick! Let me show you the difference between laminated, glass and tempered glass. So laminated glass is what they use for the front windshield. The glass is layered, meaning there's a sheet of plastic in the middle sandwiched by two pieces of glass and that's how it's held together. So you could really hit on this.

It could take multiple blows and it'll still stay together, which is why they use it for the front windshield. The other type of glass in a car is tempered glass, and this is what our rear windshield, as well as the side windows are made of. So let me show you the difference and, as you could see, you can hit this glass multiple times. It's very strong and could take multiple impacts, but if we replace this hammer with something that has a fine point to it, almost like, if a rock kicked up and hit your glass watch, this, the glass breaks up into these very small cube pieces.

And that's what happened to our windshield now before we go and replace the windshield. We want to make sure something like this doesn't happen again and while a rock kicking up is not in our control, what is in our control is checking the rear vents to make sure they aren't clogged up. So typically, the vents are located on the sides of the trunk, so behind that panel there and behind that panel there so to get to that. What we need to do is remove this plastic piece right here, so grab your panel clip pliers and we're going to want to carefully remove this panel.

Clip right here so pop that out, just like that same thing. On the other side, just pop that right out beautiful next, just pop the plastic trim out like that, and then we can remove it from the trunk and with that plastic piece removed now we could go and peel back this side panel here and check to see If our vent is clogged up, you can see the vent right there and if we take a quick look at these vents, you can see if you put your finger in here, the vents open up no problem at all. Sometimes, what happens is mice or squirrels or whatever build little nests behind here, and it prevents the vents from opening up. So when you go to close your door, the air has nowhere to go.

Normally. The air gets pushed right through this vent and it vents out, but if this is clogged the pressure will build up and you can blow out your rear glass, but in this case we are good to go so our vent isn't clogged on that side. If we come to this side i'll show you guys real quick, because i don't think this will be clogged either, but it's nice and easy to check that one is not clogged as well. So we are good to go here.

Unfortunately, it wasn't something that we could actually fix. It was just some bad luck, a rock probably kicked up or something a stick fell, whatever damaged the glass enough, since it's tempered glass a little bit of pressure, a little bit of vibration caused it to burst like that. But that's okay, because guess what that gives me the opportunity to show you guys how to replace your rear windshield using some common hand tools. So, let's get started with where you could actually buy some glass.

So there's a couple different ways to source glass. The first way is to call your local dealership and they sell brand new oem glass. The second way is to call your local glass installer and see if they'll sell you just the glass. The third way is to check on ebay.

Ebay has a ton of used glass and the fourth way is to check your local junkyard, because they have a lot of used glass as well, and that's actually where this came from now. Originally. I called ford because i wanted a brand new oem piece of glass, but they said it would take over two weeks to get and it would cost 500 - and i didn't want to leave the car like that for two weeks because it does stay outside. So i decided to go with the junkyard piece, which is perfectly fine costs 75 dollars.

They guarantee it'll work and it's in great shape. I just need to clean it up a little bit and remove some of this old adhesive. Now i real quickly want to show you guys if your glass has a heater element in it like this. I want to show you how to test it so that you know it works before you install the glass so how a heater element works in a rear.

Windshield like this, you can see all these lines in here those lines conduct electricity and they flow across. So what happens? Is the electricity comes in right here and then it flows across these are high resistance lines so that electrical resistance creates heat and then it grounds out to the other side right here. So all you need to do to check this is to grab a multimeter set. It to ohms and then grab your two leads one lead.

We will connect right here on this piece like that and we're going to connect our other lead to the other side of the glass. This piece of metal right here, and if this number changes. That means there's electricity flowing through these lines. So let's see and look at that, we're good to go.

So we know these heater lines are working. So an ohm reading on our multimeter lets us know there's an electrical connection from there across the grid to there, but it doesn't tell us if all these grid lines are working. So what you're going to do to figure that out is you're just going to go in. I put some cardboard here, so you can see it easier.

The electrical line connects right here, you're going to go across and just watch make sure there are no breaks at all all the way across. So as you work your way across, you can see that's one continuous line, just a visual inspection all the way to there. So we are good to go with that line. You want to check all the lines.

If there are any breaks, don't worry, you could repair, they sell repair kits it just paints right on, but in this case this is perfectly fine, it all works. It all looks good, we have no chips, no scratches and our glass is perfect, which is great for 75. You can't beat that. So that's how you get your glass, that's how you check your glass now, what are the tools and products you're gon na need to get this job done and, as always, i like to use common hand, tools and easy to find products.

That way, you guys could do this job at home yourself, no problem at all. The most important thing in this entire job is using a high-end urethane. This is the sealant. This is the glue.

This is what sticks your window to your car, which is obviously very important for safety reasons. We don't want that flying out. So it's also important to use a high end urethane so that you don't get wind noise and you don't get leaks so i'll, be sure to include a link to all these tools and products in the description, including the urethane. I'm using another good thing about this.

Urethane is it's diy friendly? It works with a regular caulking gun. This is a 26 to one caulking gun, so you don't need to have one of those professional, expensive, electric caulking guns with this urethane now with the urethane, you also need primer, and these are the same exact brands. I don't care what brand you use, but always match your primer and urethane brand wise so that they bond together properly and then the rest of this is pretty simple. We have gloves that are cut resistant since we're working with glass.

I have a suction cup here, that is an action, camera suction cup, so that we could carry the glass easier. We have our soapy water. We have our safety glasses, very important, since we're working with glass. We don't want glass in our eye.

Next, we have some scrapers, we have this specialized window tool. I don't think we're going to need it, but it's inexpensive. So i have it just in case helps you remove glass. We have panel clip pliers to remove panels in the interior and then we have chisels here.

These are plastic chisels. They work great i'll, show you how those work, and then we have our metal scraper. That way, we could remove the old urethane and that's really all you're gon na need. So let's go get started and the first thing we're gon na do is remove the old glass from the car and the best way to do that is to use a shop vac which effortlessly sucks up the broken glass.

So you don't have to handle it by hand, and i don't know about you guys, but for some reason, cleaning this glass up is super satisfying. Okay, so with the rear deck vacuumed, when glass breaks it could travel 25 feet so make sure you check the front and rear seats as well, and you can see there's glass everywhere. We have glass on the armrest. So, let's vacuum that up, then there's glass inside this armrest pocket get that out of there and even the window switch has glass in it pretty much anywhere with a little pocket to hold the glass you'll find glass and it's important to be thorough.

So i'm going to vacuum the entire interior of the car - you guys don't have to watch me - do that you get the idea. So with most of the glass cleaned up, it's not perfect, but it's pretty close. Now, let's get the glass that is stuck to the pinch welds you can see. We have a ton of glass right up here that if we touch this, it's all just going to fall down because it's really broken up, but we need to get all this glass off.

So how do we prevent all this from falling back down? Well, a simple trick is to use packing tape, just lay down the tape over the broken glass and be sure to cover all the pieces like this, and i can't wait to show you how well this works to keep the glass contained. So, with that excess glass around the perimeter, all taped up - that's just a real, quick tip. That's going to help you out! It's not going to make a huge mess when we go in here and we try to remove the glass that's bonded to that urethane. Now, what we're going to do is pick a corner, this one's pretty good because it has a missing piece, so we could get under here.

Grab your plastic scraper or a plastic chisel like this and we're going to chisel away at that urethane to remove it. That way, we can remove the glass along with the plastic chisel. We are using a weighted plastic hammer, so get the chisel under the glass and start hammering away the urethane and don't worry about removing all the urethane just get it so it peels up and away from the pinch weld and try not to scratch the paint and Notice, how well that tape is working to contain the glass which would otherwise get everywhere now this process does take more time than if we're going to use a professional tool like an electric reciprocating windshield removal tool, but those are over 800 and for somebody doing this, Once or twice you can see, this method works just fine. These plastic chisels were 10 bucks and you get a whole bunch of them in a set and i'll be sure to link these in the description, so you could find them now right.

Here is our window heater wire, so let's disconnect the broken glass from this wire and then, when we install the new glass i'll, show you how to reconnect it, it's pretty simple and that worked beautifully. That's why i like using these plastic chisels, you just hammer away, and it peels up all this urethane we'll get this urethane even thinner later, but right now we just want to remove the glass and the plastic is way better than metal. Metal definitely works faster, but the metal could scratch the paintwork and then, if you get a scratch over here, that'll rust and then that will be a very bad thing now we could cover that scratch with primer. But it's better if we avoid scratches in general, which is why i like using a sharp plastic chisel like this.

So now, let's remove the rest of the urethane around the entire windshield to remove it from the top pinch weld remove it from the driver's side. Pinch weld, and although this is sped up, it's really as easy as it looks and remember on this side, we also have that window heater wire. That needs to be disconnected good and, finally, we need to pop the trunk, and that gives us access to remove the glass from the bottom pinch weld and finally, we're almost done just a couple: more hits until it's removed good and with that we have removed the Glass from the pinch weld all right and we just completed the most difficult part of this entire job, and that is removing all of the old glass from our car. I also ended up vacuuming any little bits and pieces that came flying off.

So all the old glass is removed and it is all in this box. This is the proper way to get rid of old glass. You put it in a box, not a bag because it could cut through a bag and then seal up this box, and this is how you'll throw out or recycle your glass. So no one gets cut so now, there's only three main steps left.

The first step is to prepare the pinch weld on the car for the glass. The second step is to prepare the glass for putting onto the car, and the third step is to actually put the glass on the car, and all these steps are really straightforward. Easy to do i'll cover all the information, so you know exactly what you guys need to do. So, let's get started now what i mean by prepping the car surface is we need to get this surface ready for the brand new urethane we're going to lay down a bead of urethane right on here? But surprisingly, we don't want to remove all of this old urethane.

We just want to shave it down. So there's a fresh new layer, that's like one to two millimeters thick max, but before we do that, we want to make sure that we clean out all of this old gunk in here, because that fresh urethane can't get contaminated. That's a really good surface for the new urethane to bond to, but not, if there's all this junk here and it gets on that fresh urethane. So the first thing we need to do is clean up the pinch weld around the car and you don't need anything special.

You just need some soapy water and a lint-free towel just spray this down here and clean out that pinch weld removing all the dirt and debris. That's collected there over the years and check this out all the dirt we removed. This is what we don't want to contaminate our freshly cut urethane. So it's a good thing.

We clean this off and you can see how dirty these pinch welds are so clean them up with some soapy water and a lint-free towel. Just like that and work your way around the entire window frame spraying it down and wiping it with your towel, like so all right and check out how clean this pinch weld is all the way around the entire car that looks awesome now before we go and Shave down our urethane, so it's one to two millimeters thick. What i want to do real, quick is we're. Gon na have to install these wires into our heated rear windshield, but this plastic trim is gon na get in the way and i'd rather not put the glass on and then try to figure out how to get this out.

So, let's remove the plastic trim now, so we don't have to worry about this getting in our way and it's pretty simple to remove this first use a plastic trim removal tool, so you don't damage the plastic trim and pry this cap, open and inside of here Is an eight millimeter bolt? We need to remove good and then we can just pop this panel out like so and carefully remove it same thing on the other side pop that cap open unscrew, that bolt holding it in and pop that trim out, and you can hear that glass in there. So be careful, remove it and contain the glass, so it doesn't get everywhere good, so, with both of the plastic trim pieces out of the way we have one last thing: we need to do to prep our car for the new glass, and that is to shave Down this thick piece of urethane bead, that runs around our entire pinch weld and to do that we're using a brand new razor blade, because we need this to be extra sharp, but anytime, you use a new razor blade. They coat these in oil, so it doesn't rust in the packaging. So it's very important that you get a towel with some isopropyl alcohol on it and carefully clean off all the oils that are on that razor blade both the front and the back.

That way, we don't contaminate our fresh urethane. Also, the corners of these razors are really sharp. So as we go in and try to scrape up that urethane, you could easily scratch the paint on the pinch weld. If that paint gets scratched, rust could start forming, and if that rust bubbles up it could lift the glass up.

You could get leaks or even worse, that glass could start lifting up and come off. So rust is the enemy we need to avoid it. So a way to protect the corners of your razor, so it doesn't scratch easily, is to use tape and just fold over the tape on each of the corners, and then you can even rip it off so that the tape is a smaller profile. It's not in your way, and it should look something like that.

So now our corners are protected, so we're less likely to scratch that pinch weld paint. So now let me show you how to remove the urethane and now you're going to glide that blade as flat as you can, along that pinch, weld underneath that urethane almost like you're filleting a fish and leave behind this beautiful flat, one to two millimeter thick urethane Surface, that's nice and fresh. That's exactly what we want! That's the perfect surface for our new urethane to bond to so now we want to shave down all the urethane, so it's one to two millimeters thick just like that, and you can see right here where i shaved it down a little bit too far. This is inevitable: you're gon na get scratches you're going to shave it a little bit uneven.

It's going to happen, you're not going to be perfect. Don't worry! This will get covered by primer. That way it won't rust and also so. The new urethane will bond properly.

Now, if you're doing this and the weather is cold, the urethane is a lot harder to cut. So a trick is to carefully heat it up using a heat gun, just keep that heat gun moving and don't hold it in one spot which could damage the surrounding paint now, even in the colder weather. Look how easy this urethane is to cut that razor cuts through it like a hot knife through butter, so work your way around the entire window frame for laying the urethane, nice and thin off the pinch weld all right. So we're finishing up at the bottom of the window frame, and this is just going so smoothly, and it's so satisfying who says replacing your windshield doesn't have to be fun now something very interesting.

I want to show you guys, while i'm shaving the urethane down here, check this out. This is from the factory. This is a factory mistake, they put sound ending over here and they put the urethane over the sound deadening. That is not right.

Sound deadening is not something you could bond to. You have to bond straight to the metal surface, so scrape up the sound ending as well as the adhesive under it. So we can lay down our urethane straight to the pinch weld and to remove any residue just use a towel with some alcohol on it, and the residue will come right off. So with that sound, ending and the adhesive completely removed.

Now we could properly apply our urethane in that area, never apply your urethane to anything except the pinch weld. It should never go over sound deadening. It should never go over carpeting, nothing except that pinch weld and i'm very surprised. The oem manufacturer did that because that's incorrect, but we fixed the problem and we removed all of the urethane around the pinch weld we shaved it down to make it nice and thin.

So we are done prepping our car. Now we need to prep our glass and this process is very similar. Now, if you have new glass, this is a lot easier, because you don't have to do half of the stuff we're about to do, but because we bought inexpensive, used glass i'll show you how to prep it. So, let's start by removing both of these wires from the heater element, since we already have these built into the car next, what we need to do is remove all of this old urethane around the entire border of our glass, and we need to completely remove it.

We don't want to even have a sliver on here. This isn't like the car. We need to completely remove all of the urethane, so we have a fresh glass surface because then we're going to put primer down. So, to do that, i have this tool that works very well, it's a razor on a stick, and this is great.

It gives you the leverage you need to help peel this up. Now all you need to do is just get the razor under the urethane and scrape it along the glass like so, and make sure you point that razor down at a 45 degree angle against the glass don't be afraid to scrape the razor along the glass trying To remove as much urethane as possible, the razor won't damage the glass, so you don't have to worry about it like we did with the car paint, so work your way, all the way around the glass, removing the old urethane and we're coming to the end. Here with our last bit of urethane to remove beautiful, alright, so with all that urethane removed from the glass now we need to get down to the bare glass surface and to do that, we're just going to go along the glass like this scraping back and forth Until there's, no more urethane left i'm putting medium pressure downwards into the glass to make sure that blade is scraping as close to that glass as possible, and you can see there's small amounts of urethane still left on here, but it's coming right off and now this Is nice and smooth and urethane free all right and check out our glass? It is looking absolutely amazing. Nice and smooth all of the old urethane is gone.

The dark spot is just the old primer and don't worry, we're gon na add new primer. You can't remove that unless you like sand it down, we don't want to ruin the glass, so we're gon na just keep it like that. That is perfectly fine. At this point, it's almost like.

We just got new glass. So now what we need to do is follow the instructions on our primer. This is a single step primer that we're going to use around the edge of the glass and we're going to use on the pinch weld. So we want to make sure we follow the instructions exactly, and the first thing we need to do is spray the glass down with glass, cleaner and clean it off, and when you're cleaning glass, with heater lines like this right here, this heater line right there you Want to make sure that you go in the same direction with the grain.

You don't want to go against the grain of the heater lines, because that could damage them so be sure to wipe the towel with the grain along those heater lines and wipe the entire windshield down. So there's no oils or residue all right so with our glass completely clean before we go and add our primer, what we want to do is dry test fit this so grab your suction cups. This is a professional suction cup. I'm not going to use this, but you can buy them they're, not that expensive.

What most people have already is an action cam suction cup. So that's exactly what we're going to use so wipe down the glass and stick that suction cup on tight and that's not going anywhere same for the other side and i'm using a bigger camera suction cup here, and this has three suction cups. So we're not going to have any problems at all. Now, i'm going to flip the glass around, so it's oriented in the correct direction and when you flip this over, you can see our alignment.

Pegs are on top of the windshield now and i'm going to show you how those fit into the car so right here are the two holes. Our alignment pegs on the glass are going to fit into. Not all glass has this, but many do so. If yours does, it will make your life that much easier and help you align the glass properly.

So right now we're just practicing to see what it's like to install the glass and you can see it actually fits right in there pretty easily. And although we have those alignment pegs a little trick to help make it easier to line up, the glass correctly is to use two pieces of tape to lay them across the roof and onto the glass one on each side and cut the tape. So you can remove the glass now you can line these pieces of tape up when we add the glass later and that just makes lining everything up easier and you definitely want to make sure that you test fit your glass. That was a perfect dry run.

You don't want to do it when you have the urethane on and then you have one shot, it's good to have some practice and get those alignment marks as well. Now we're almost ready to add our primer, but before we do that we have a piece of window trim. I didn't get a new one, i'm just using the factory one it's in good shape and it goes on the back now to install our rubber trim. Molding onto the glass, all you need to do is slide it onto the edge of the glass making sure it's even on each side and then, once you have it in place.

We're gon na press down on the rubber molding to stick that double-sided tape onto the glass. Don't worry when we add our urethane to the glass later, it's gon na squish against the molding and hold it in even stronger and that's how you install rubber molding onto the glass if your car has it so with our molding in place. Now we're ready to add our primer, and this is very important. This gives you the proper bond from the glass to the urethane.

That way, it doesn't separate - and it's very important on the car as well, to prevent rust for any spots that we scratched, and the first thing to do is to make sure your primer is not expired. This isn't that's very important and then shake it up for a minute. You should hear a metal ball banging around in there just like a spray paint can and finally, the last thing you're going to need to spread out. The primer is a dauber like this.

These are inexpensive again i'll link it all in the description, so you can easily find it. Let me show you how to apply this, so, let's dunk the dauber into the primer and then lay down that primer onto the glass following the old primer stain. It's that simple, so work your way around the entire perimeter of the glass covering the old primer and making one continuous bead of primer all the way around, and you want to make sure your primer is going on evenly. It's not thinning out as you apply it, and this is looking great, and one thing i definitely want to mention is this: stuff has a really strong odor and it's not good to breathe in so make sure you're working outdoors when applying this and if you're indoors, Make sure you have ventilation or a respirator on so you aren't breathing this in now.

We're rounding this last corner here coming back to where we started and we are done and now our glass is completely done. This is prepped and ready to go. All we need to do is let that primer dry for at least 10 minutes before we add this to our car, so with the primer on the glass drying. Now let me show you how to add primer to our car, and this is completely different, so we have a fresh cut urethane right here and we do not want to get primer on that fresh cut.

Urethane. This fresh cut urethane is the best bonding surface for our brand new urethane. What the primer is for on the car is for spots like this. You see where we go down to bare metal where there's no more urethane same thing right.

There there's another spot. Those spots will rust after we add our new urethane. Also, the new urethane won't bond the best to this. It bonds best to primed surfaces, so the primer stops the rust and makes sure that it bonds properly.

Now. One thing i do want to mention we're using black primer, and this is a black car, so we don't have to be super careful with where we put this. If you have a white car, though anywhere you get primer, it's gon na stain so make sure you keep it underneath the glass now for these bare metal parts on the pinch weld just cover them up completely with primer, so they don't rust. Just like that and same thing for any smaller pieces of exposed metal like this right here as well as this bare metal right here, where our hole is for the glass alignment peg.

So now you just want to go along the pinch, weld and very carefully. Look for any nicks or scratches like that right there. You can see that little nick, it's very important, that we cover even that little nick to prevent rust and after that spot's covered continue around the pinch, weld touching up anything that you could find like this scratch right here. It's small, it's narrow, but it needs to be touched up or it could rust.

So i went around the entire pinch, weld touching up all the little nicks and scratches i made with that primer and we are good to go now. We need to let this dry for 10 minutes and as this dries, let me show you how to cut the urethane tip. So when we add our bead of urethane, we want to make sure the tip is the proper shape. We don't want to just cut it here and have a round bead.

We want to have a triangular bead. The reason why is because, with a round urethane bead as it gets squished down by the glass, it doesn't have as much surface area contacting the glass or the pinch weld now with the triangular bead as the glass squishes down, it creates a rectangular shape and that Contacts much more of the glass and pinch-weld surface, creating a stronger bond. So, although it seems like a small detail that makes a big difference on how well this glass adheres, so you might as well do the best job. You can.

Let's cut this into a triangle, and the first thing we're going to do is we need to make sure our tip is a quarter of an inch. So the tip of our nozzle, where the urethane is going to be coming out, has to be a quarter of an inch wide, and i have our digital caliper set to a quarter of an inch and i'm just going to slide this across. You could also use a ruler, and you can see right. There is as far as it's going, so that is one quarter of an inch now.

What i'm going to do is i'm going to take a razor right where that quarter of an inch mark is, and i'm just going to cut straight down. Just like that. So now the tip of our nozzle is a quarter of an inch in diameter, which is the correct diameter for applying our urethane. Now let me show you how to measure how high our triangle has to be so to get the correct height for your specific vehicle.

Come over to the pinch, weld and push the tip all the way down into the pinch weld, and this top surface right here, where the glass sits flush is what we want to use to mark the height of the bead and i'm just using a piece of Tape to mark it now we could use a marker to outline the two cuts you're going to make to make the triangle and then carefully get your razor and cut along those lines and don't worry if your cuts aren't perfect. You just need to get that triangular shape and you'll, be fine and then make sure you shave away any loose plastic sticking out, so it doesn't break off and contaminate your urethane good and that'll work. So with the tip cut properly. We are on our final step and that is adding our urethane.

So first we need to poke a hole in the urethane container and don't poke a little hole. We need to make sure it's big, because this is pretty thick and we need to make sure it flows, so you can see that hole is completely opened up. So now, let's add our tip and this screws on like so then we could remove the rear cap which keeps this air tight, so the urethane doesn't get hard and then add the tube to the caulk gun and we are ready to go now. What i like to do is fill this up with urethane and shoot a practice bead also.

Another thing i do want to mention is as we're doing this. You never want to add your urethane like this. You don't want to drag it across like that, because you're just kind of laying it on top. You want to force that urethane into the pinch weld, so you want to point it perpendicular like that, so you're pushing it into the pinch, weld to give it the best bond possible, and you always want to do a practice run before you lay down the urethane On your pinch, weld and this first practice speed - isn't that great, because it's leaning over so let's try that again and we want the beat to stand straight up and not lean over, and this is looking way better.

So now i have a good feel for it and i'm ready for the real thing all right and finally, the last part is laying down our bead of urethane. I like to start in the bottom corner here, so we're going to lay our bead down here and we want to try to have one continuous bead if possible. If not, no big deal, don't worry about it. We could paddle the ends together, but you want to try to be as smooth and even as possible all the way around and the bead should be in the center of this urethane here.

So, let's start at the bottom here and make sure your triangular bead stands straight up like that, and this looks perfect and around this corner. That is not really that good, it's falling over a little, and i need to go a little bit slower on the next corner, but don't worry, we could straighten that up when we're done and while corners are a little tricky. The straight parts like this are really easy to lay down, even with a manual hand, pump caulk gun now coming around this other corner, i'm going a little slower and check it out, that's way better than the last one, and that's exactly what you want to see When you're going around the corner, so i think you get the idea, take your time and lay down a continuous bead right over that fresh cut urethane and make sure it stands up straight. Okay, so now we're almost completely around the windshield frame and when we get back to where we started, we want to run this bead a little bit past the starting point.

So there's overlap now anywhere. You don't have a continuous bead like where you start and finish your bead. You can see. I overlapped the two beads and what we're gon na do now is called paddling, where you push the two beads together to make it one bead you wan na use something flat and non-porous, and i'm using these plastic razors, and this specific urethane is very sticky, which Is good but it makes it difficult to paddle, but you get the idea.

You just want to make sure it's combined into one piece and you also want to make sure it's standing up and although it doesn't look pretty, we are good to go so now. These are combined into one and we don't have to rely on the glass pushing down and squishing the urethane together, because if it doesn't you're gon na get a leak, but since we did it ourselves, we know we won't have a leak. Now real quick. Take a look at how good this came out.

It's not difficult to do at all, and if i could get results like this, while filming you guys could get even better results without a camera in your way. So after you apply this, you have about 15 minutes before it skins over. So let's not waste any time and go get our glass on the car. Okay! So take your time here and lower it down carefully and don't let that glass touch the urethane until you know you're aligned, because once it does, the urethane will stick to it and we can't lift up after that all right.

So i'm good on my side, ready to lower it down good all right and we are in there. You go all right so with your glass set in place, do not press down on the glass just yet. The first thing you're going to want to do is check the panel gap between the panel and the glass and make sure it's even all the way down, and that looks really good. I checked the other side already, that's nice, and even so, both sides are even and we're good here.

But, let's just say one of your sides isn't even let's just say the glass is too close to the panel. So all you would do to fix an uneven gap here if the glass is pushed up against this piece of metal, we need to move the glass that way, but very very slightly. Just a millimeter or two is all it takes once the glass is down. You can't make big adjustments so with an open hand carefully and lightly push that way, keeping an eye on that gap and once that gap opens up, so it's even you're good to go after your glass is in your panel gap is good now you're going to Take an open hand and press down around the perimeter of the glass pretty hard.

You want to make sure that you seat this very well all the way around the entire perimeter of the glass and then after you do that it's seated it's squished down against that! Urethane now you're gon na grab some tape and you're gon na tape. The top of the windshield like that and like that and what that's gon na do is that's gon na help prevent the window from sagging downwards because of gravity, so you're gon na make sure that it cures in place, and this takes about 24 hours to cure. For this specific urethane next go around the car and inspect where the glass meets the pinch weld, and you can see right here. We have some primer, that's clearly visible, so before it dries, we could easily fix this.

Just get a towel with a little bit of alcohol on it and wipe it away. Like so - and i have another spot right here - and you want to clean these up now, because tomorrow it'll be fully cured and it won't come off easily and finally, a few more quick tips leave your suction cups in place. You don't want to try to lift them off the glass and then lift the glass up by accident, so it's better just to let the urethane cure, and then we can take this off tomorrow when you're closing your trunk. Do not slam the trunk you're going to want to lightly close the trunk like that and then just press down and then finally, one more thing you could do is you could open the window on your car? Opening the windows of your car, just a crack, will help equalize any pressure inside the car and if you open the door and forget - and you slam it by accident, it won't push air through that new urethane and it won't separate that window from the new year Thing the air is going to escape through that open window instead.

So those are some quick tips to give you the best possible results. So now all we need to do is wait 24 hours for our urethane to cure and we're good to go all right. Now. 24 hours later, our glass is completely cured and just to make sure you could go over to your test piece here and make sure that it is completely cured.

There's no gooeyness, no stickiness. It is completely solid, so we know our urethane is cured. Now we can remove all the tape from the windshield, because it's not needed anymore same goes for the suction cups, and these worked great next use your favorite glass, cleaner and spray down the glass, and we want to clean up any suction cup marks, as well as Any dirt, so our glass looks brand new and don't worry, i'm going to show you how to easily remove that marker from the junkyard. That's on the driver's side of the glass so to clean off this marker just take a razor and lightly scrape the glass.

The razor isn't going to scratch the glass but it'll clean the paint off no problem, beautiful, oh baby, and look at that glass. That thing looks brand spanking, new, so good and for 75 dollars, but we're not done yet. We still have to connect our window defroster. So connect the wire to the defroster grid and make sure you hear a click to know it's fully seated.

Then we can get the plastic trim piece in place and press on it, so it snaps in then just hand tighten down that bolt that holds it in and finally push the cap in. Just like that now we have to connect the wire on the other side and watch this boom done all right. So with both plastic pieces in there. The last thing to do is to start up the car and test it out and with our engine running we'll.

Come down here to our climate control and we'll hit our rear defroster. Now we just have to let that sit for like 5-10 minutes and 10 minutes later. Let's check this out, let's see if we can feel it alright, it is warm warm warm. It is warm across the entire windshield and i have a really cool way that i could prove this to you guys so here's my thermal imaging camera capturing the window heating up with a five minute time lapse, blue and purple are colder, yellow and orange are warmer And it's so cool, you could actually see the grid lines heating up the glass.

So now the glass is toasty warm and you can see each individual grid line is working perfect. Just like we tested for beautiful and finally for one last test. We need to make it rain. I want to prove to you guys that we have no leaks, so i'm simulating a heavy rainfall and check it out.

Not a drop of water is getting into the car, so we know this is sealed perfectly so there you go. That's everything you need to know on how to replace a broken rear windshield properly and if you guys were wondering if you have to do the front windshield, it's almost the exact same process. The biggest difference is removing the old glass with the front windshield. It comes out as one big piece.

That's the only difference after that everything is the same, so you'd follow the same exact process, so there you go.

    me: has no intention of ever replacing the rear window by myself because insurance would cover it
    also me: yo let's watch it anyway

    The only thing I wish you would have included was removing the glass from the junkyard car. I have a car I'm restoring and the windshield is cracked and my best option is a junkyard windshield

    OR Chrisfix broke the glass on purpose to make a video. not buying the whole close the door and it breaks. I mean its Chrisfix he has his cars well taken care of. anyways thanks for the video. I've been wanting to replace the front one. since I got a rock chip on it on a road trip. dead center too. no spreading lines yet.

    I think the way you work is better than the factory
    I have a question that puzzles me a little
    Do car factories wait 24 hours for the adhesive to dry?
    Or they have a quick way to dry the adhesive

    chris I learn a lot of DIY because of you because you teach us step by step in easy and simple terms. you are a blessing. fan from 🇵🇰

  13. Avataaar/Circle Created with python_avatars Peter Pawlak says:

    Every one of my cars that have had the back glass break it ruins the rear deck speakers. They instantly sound blown and can never get every little piece out

  14. Avataaar/Circle Created with python_avatars No U says:

    i didn't know there was a electrical connection on the glass itself, always thought there was a vent to blow for the rear defroster.
