Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the window sash connectors on this Alero. This is a two door, it's the same for the four door also same for the Pontiac Grand Prix. When these sash connectors go bad, sometimes your window will get very crooked or the window will work correctly going up but then you go to roll it down and it sounds like something's working but the window doesn't actually go down. Those are usually the signs that your connectors are broken. Tools you'll need are an 8mm wrench, small flat blade screwdriver, Phillips screwdriver, 10mm socket and ratchet with extension, a heat gun, a putty knife, a razor blade and holder, mineral spirits/some type of solvent, also Isopropyl rubbing alcohol could work, and you'll need urethane adhesive that works on glass.
Use your 8mm wrench and disconnect your negative battery cable.
You're going to start under your door pull. There a little trapdoor here and, either from the top or bottom, just pry that off and there's two Phillips screws in there. We'll speed it up here a little bit as I just remove those screws. I'll use fast forward quite often when I'm just doing monotonous tasks like this. Now, right up here, you just pull on this panel. It comes off. If you have this speaker here, just use a screwdriver, pry up on this tab and disconnect it. Also, down in this corner, use a little screwdriver and pull this reflector out. Inside here there's a Phillips screw. Once you have that out, use a door panel clip tool or a putty knife, start anywhere and, then slide until you feel a clip and, with the door panel clip tool, you go around the clip, and then pull, and that screw comes out. Put it in the car. I can see back in here, can see where the clips are. Then, just work your way all the way around the door. Once you have the door pretty loose, it comes out and lifts up. For your door lock, just pull back on this tab, and disconnect it. Then these two switches just have tabs on them. For this one, I'm just going to reach underneath and pull that one off. This mirror switch is a little more difficult. There's a tab right here, use a little screwdriver and force it up. I just take my screwdriver, force it up in there, pry that down and that release. Then the last one here is my trunk switch, which, again, you just use your screwdriver for. There's a locking tab right here. Pull it off. Carefully remove the water shield.
Reconnect your battery and your switch and move your window up or down until you can see the two bolts that hold the sash connectors to the regulator. This 10mm bolt here and then there's another 10mm bolt right here. You want to remove those. Those hold the window to the regulator. Once you remove those two bolts, you can grab the window and pull it out. To remove the window, you take this piece of weather stripping and pull it right off, allow the front to fall down in, pull the back up and out and pull the window out.
I'm going to fast forward here. This isn't in real time, I probably heated each side of the connector a couple of minutes with the heat gun then get the putty knife underneath there, release the adhesive and it comes off. Then start rough-scraping the window with your putty knife. Continue cleaning the window. Now, I'm using a razor blade holder and a razor blade. Now, I'll slow down here. I actually use a permanent marker and mark the position of the connector before I lose too much evidence of where it was. Just mark its position and then continue cleaning using the razor blade then using a chemical agent. I used mineral spirits; Isopropyl rubbing alcohol can work, as well. I also, when I clean the side that I marked, I mark the other side just so I make sure I don't lose where that position of that connector is.
Now the window is clean and marked, ready for installation. Use the other one as reference so you don't install the connector upside down accidentally. We're going to use a good urethane-based glue. You've got to make sure the adhesive you use is urethane based and also make sure it works on glass. You want to slide that right on, and put it right in place, right between my marks. Now, I'm going to actually put it right up, stand it right on there and let it cure. It kind of goes without saying, but I'll say it anyways: make sure you read the directions of the adhesive you use and then just monitor it. Usually the adhesive like this has to cure for one or two hours. Make sure it doesn't drip onto the connector or anything and may be cause problems for installation later.
Put that end in first, and then slide it up into place, and then slide it down to the window regulator. Put that in there. Put that one in there. Make sure it goes down correctly. Now, I've started those two bolts that hold the regulator to the window. I'm just putting that piece of weather stripping back in place that I took apart to get the window out and then I tighten up those two bolts. You can test it and you're pretty much ready to put the door panel back on.
I've hooked the battery back up, and plugged my switch in. Probably a good idea to just put the window up in place, all the way up. That way your regulator is pushing up on that connector. Let it cure that way for a day or two.
Carefully put your water shield back in place and you're ready to put the door panel back on. Plug in our lock switch right up in here and our mirror. Push this in a little bit. Here's the power window switch and this one goes down to our trunk switch. Then, make sure you push the top of the door panel in. Make sure this speaker lead is up out of there. Push the door panel down into that channel. You may have to use your putty knife or your clip tool to force the upholstery in there a little bit. I'm going to peek back in here, and make sure your pins are going in where they should. Fast forward through reinstalling those three Phillips screws. Put your reflector back in, put this panel back on, plug back in your lead there, and put that back on.
Then reconnect your negative battery cable.
