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 a rear window regulator on this 2003 GMC Envoy XL. It's the same part and similar process on the regular Envoys from 2002 to 2009. The items you'll need are a new rear window regulator from 1AAuto.com, flat blade screw driver, a 7mm and 10mm socket and ratchet, and a putty knife.
Start off by prying up this little cover with a flat blade screw driver. Then remove those two 7mm bolts. Stick a putty knife behind the door panel and slide it down until you find the first clip and pry out and reach in behind the door panel and just pull out around each clip. Once you remove each of those clips, you can pull the door handle back. Then just push this switch from underneath. It comes up and out. Then push the tab on the harness and disconnect it. You could technically do this before removing the door panel, but you're more likely to scratch up your door panel if you do that. Remove your water shield. Having a razor blade can help because you can just cut at the adhesive, but you can also just pull it free.
This is a cable activated regulator, and a lot of times when they break, what you'll be able to do, you'll hear a popping and grinding noise, and then your window will actually move up and down. So, once you get the door panel off, you'll want to move it to this position where you can get at this 10mm nut and this 10mm nut, and you're going to loosen those. Before we do that, we'll just take a screw driver and push on this tab here and push the connection out. Pull the window up and out of those clamps. Then push the tabs on this clip and push it through the door. Then remove these two 10mm bolts and loosen this top one. Tilt your window regulator and then lift it up and unhook it and pull it down and out of the door.
On the left is the old regulator. On the right is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same. Remove that top bolt from your old regulator and thread it into your new one just loosely so that you can hang it up in the door. Take your new window regulator, feed it up into the door, push that bolt through the top and hang the regulator and then just line it up and replace those other two bolts. We'll fast forward as Mike does this and tightens them both up. Push this clip back into the door, loosen up these window clamps, reconnect this harness, and then slide the window down into those clamps. Once you have it all the way in and clamped down, tighten up those two 10mm nuts, put your vehicle into accessory, plug in the switch, and just test out the regulator. You can see it works. You can just disconnect the switch and make sure you put your car back in the off position.
We'll fast forward as Mike replaces that water shield. To replace your door panel take the small panel and push it back onto these studs. Then, push the harness for that switch back up through the hole in the door panel. Line up the clips on the door panel, and once you have them all lined up, just hit them into place. Reconnect the switch and push it down into place, and then replace those two 7mm bolts and tighten them back up. Now just replace the small cover, and you're all set.

We have only had a chance to try it this summer after installing this spring. Has worked just fine. Does not drop the window completely below the opening, but enough to serve the purpose even if you lean your arm out the window
Easy to follow

The video gives clear and precise directions. It is easy to follow along step by step. All you need are the tools and the basic knowledge of how to use them. He goes through the steps fast so I had to pause and rewind the video several times but that was to be expected because I've never done this before and wanted to make sure I was doing it right. This is the first 1A auto video I've used but it won't be the last. I highly recommend.
No problem

The the problem solving videos and parts for repairs have made it possible to solve numerous problems for mine and my families cars. I have shared this technique with my grandsons for car repairs.The window regulator is just another example which probably saved me several hundred dollars and was not difficult to do.

1st order from 1A auto and I couldn't be happier. The part was a perfect fit for an incredible price. The online video was spot on for how to replace my defective window regulator. Thanks for the great service!
Works, but...

The window regulator fit and works, but... The motor was wired with reverse polarity so the switch works in the opposite way from how it should. This is not uncommon. There's a 50/50 chance to wire it correctly and apparently the manufacturer (and other aftermarket manufacturers) don't consider it worthwhile to verify their products. I'm living with it as is for now, but might switch the wires eventually to correct the polarity. 1A's response and service has been great, they offered to exchange it, but I don't consider it worth the trouble since it is usable as is.

The true indication of a company is how they respond when something goes wrong with their product or shipment. 1A Auto showed their true colors by standing behind their product that was damaged by the shipper. 1A provided the replacement part quickly when my original part was damaged in shipment. One of the best parts of working with 1A is the videos that they provided showing how to replace the parts. The one for my windon motor and regulator was very well produced. No randum comments, just plain, easy to follow instructions with clear video. Made replacing the window motor and regulator a since. I am happy that I found them on the web and plan to use them next time I need parts for my trailblazer

You will need 1/4" bolts , nuts, and washers to insert where the rivets have to be drilled out and masking tape to hold window. It's I believe 5 rivets that you drill.

Just the tools to take your door panel off and the few screws that holds tue regulator

I did not need any other parts the first time I did it years ago. I never got around to it the second time it needed it as we bought a new car and the trailblazer turned into a junker commuter that isnt worth putting time into. Any interest in buying the regulator I didnt use?

Nope. Direct bolt in. Use your current bolts. Easy
