Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing or maintaining your vehicle. I'm going to use my 20-plus years experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1AAuto.com. The right parts installed correctly: that's going to save you time and money. Thank you and enjoy the video.
In this video, we're going to show you how to replace the rear window regulator on this '02 GMC Sierra crew cab, same as any '99 to '02 GMC Sierra or Chevy Silverado and same as the later ones except the door panel removal might be a little different. Tools you'll need are a flat blade screwdriver, a 7mm socket with a ratchet and extension and a 10mm socket with ratchet and extension and a little bit of painter's tape as well.
There are two 7mm screws that you have to remove or bolts: one right in there and then one down in the bottom corner here. As well, you need to pry out this trim panel, pry out your lock button and pry out your window switch and disconnect it. First, put your finger under them. Pull out that bezel, take a regular screwdriver, stick it in the front there, and pull out your lock button. For your window switch, also pry out gently there. Get the front of it and then there's a little tab, use your screwdriver, push on it, pull the connector down and out. You can also pry out your light and reflector and disconnect it. Then use your 7mm socket and ratchet and extension. We'll just speed up here as we remove those two 7mm bolts. Once everything is unbolted then you just lift up on your panel and it comes off. Fast forward a little bit here. Slowly and carefully . I know I'm fast forwarding, but please slowly and carefully pull back your water shield so you can access the inside of the door panel.
I actually have my key on and my window switch is in. You can see that the window is clipped in by two 10mm nuts here. You tighten these and they tighten these clips up. Usually what happens on these regulators is the cable snap and in that case you can bring your window up and down anywhere you need it and, as you can see, there's plenty of room in this door that if your window motor is broken and it won't move, you should be able to get in there and get at them. You can easily remove this speaker with three 10mm bolts here and the last thing down here is my window motor. Just push on this tab. If you want, use a screwdriver to push that tab down and out. I'm going to use my 10mm socket and ratchet and extension to loosen up these two nuts. You can see our window is down a little bit. Once those are loose, you can just take your window and push it up into place. Just use some blue painter's tape to make sure the window stays up. Remove these two lower nuts. Now just loosen these two upper ones a couple of turns. There's a bolt right here that holds the window motor, way down in the corner. We'll just speed this up a little bit as I take that lower bolt out. The regulator can go out, up and your regulator comes out.
Here's your new regulator from 1A Auto; you see it's all the same as the old one. Feed it in the exact same way, here. Make sure you get your wires on the correct side down here. Also make sure the regulator is on the inside of the window. The bolts they put on are a little too big to go through those slots. What I'm doing here is the upper bolts you can leave in the regulator and you just hang them up in the doors, they go through larger holes and then slide down into slots. The bolts that came in the regulator, the heads were just a little too big to fit through the larger part of the hole so I'm just threading them out and putting them into place and threading them back in. Fast forward here as I start that lower nut on, then I align the other rail, get it in and start that nut. Continuing to move quickly here, I start the bolt that's in the lower corner of the window motor and then I take my ratchet and socket and extension and tighten all those five bolts up. You tighten them up firm but not extremely tight. I've got my key on. I'm going to plug my window motor back in and, now, I'm going to run my regulator up. Loosen up these nuts here. Remove my tape. Bring my window down, make sure it goes into the clamps here. Get a little bit of mild hand soap and grease the window a little bit. Get some down in these clamps. Move the window down, and make sure it's going into the clamps where we want it to. Push it down into the clamps. You may find that you want to loosen them up a little bit more. There will be marks on the windows and you just want to line them up in the same place and use your ratchet and extension and socket and tighten those clamps up. Again these don't have to be extremely tight but you want them nice and firm. They'll grip the windows. I still have my key on so I can test the window, bring it down and bring it back up. We'll fast forward again here. I just tighten those clamps up a couple of turns, disconnect my switch and then start putting my plastic shield on.
When you're putting this all back together, make sure this harness goes through this upper hole and make sure you put your lock rod through this lower hole here. Now in the interest of keeping this somewhat manageable as far as length, I'm going to fast forward through putting the door panel back on. If you want to see this in regular speed, just check out our other videos for the Sierra and Silverado crew cab rear door panel install and replace. Once you get the door panel back on, it is a pretty easy process. You put it back on, slide it down, insert a couple of bolts, put on the trim panels and you should be all set
