Bought this for my '03 tahoe due to motor failure. This assembly fits exactly, and thanks to a good youtube video got exact steps to remove old and install new efficiently the first time. Now my window works again! Thank you Dorman for a history of affordable and working replacement parts!

This is a great product for the price. My dad was having problems with the driver side window motors going bad like once a year so we tried everything and after hearing about the window tracks in these trucks going bad I decided to take a gamble on just replacing the whole thing and I’m so glad I did. No matter what we did the motor was having problems after about half way with a new motor sometimes we had to pull on it while pushing the button up which shouldn’t happen. After installing the thing works so good it’s never when up that fast since he’s owned it. My advice is if you own a Tahoe,suburban,Denali or Silverado to just get this complete kit it saved so much time and money I would definitely buy again no hesitation

Great fit, took about 30 minutes to install. As other reviews have said, a screwdriver/prybar, 7mm socket, and a 10mm socket are all you need. To remove the door panel, pop off the sideview mirror cover, take out the bezel for the door lock, and remove the bezel for the door handle. All of them are held in with clips, so use the screwdriver to pry them out. Unscrew the bolt behind the door pull/arm rest with your 7mm socket. Lift the door panel straight up and out of the hook slots. Before pulling it away too far, disconnect the little marker light at the bottom, and the switch connectors. To make things easy later on, pull the switch module out of the door panel by releasing the 4 tabs that lock it in on either side, and slide it out. Peel back the vapor barrier on the door, but leave it hanging on the door, because you have to reapply it after. I found it easy enough to remove the door handle at this point so it wasn't in my way. Just pry off the spiral clip holding the rod to it, then undo the 10mm bolt holding it on. Slide the assembly forward, and it comes right off. This may or may not be a necessary step, I don't remember. I just did it instinctively. Tape your window in the up position to the door frame. Loosen the 2 bolts that hold the window to the regulator. Plug the switches back in and roll the "window" down so it releases the clamps from the window. Now disconnect the switches again, disconnect the connector going to the window motor. At this point, it's pretty much as simple as pulling the 5 or 6 bolts that hold the regulator rails in place, and slipping them out. It may take some maneuvering, but there's plenty of room. When putting the new regulator in, make sure you've pulled all the bolts out before hand, and remove the 2 nuts at the bottom. I found it easier to put the motor side in first, then carefully collapse the cable to slip the neutral side in. Line the studs up with the holes in the door at the bottom of the rails, and put the nuts on (loosely). Now you should be able to pivot the top into place to install the new bolts. If I recall, I think I needed to use 1 of my old bolts (near the motor support) but for the other holes, I used the new ones. Tighten everything up, and plug in the motor. Now connect the door switches again, and run the motor up so that the clamps seat against the window. It's a good idea to reach in and push them up snug against the window when tightening the bolts here. Make sure that rubber pad is in place when you do it. Also, make sure the rubber pad from the previous regulator is removed. One of mine was stuck to the window when I pulled the old regulator out. Assembly is reverse of disassembly. Don't forget to reconnect the rod for the door handle. I have years of automotive experience, but this is my first window regulator replacement. Total time, 30 minutes. Tools were a 10mm socket nut driver, 7mm socket nut driver, and a standard flat head screwdriver. These rails are greased, so keep some shop rags or paper towels handy when you do all this. Performance: Rolled my window up and down for the first time in 9 years. :D Motor didn't seem like it was struggling, and it moves faster than my factory drivers side motor. Needless to say, that one is probably near the end of its lifespan too. I'd be more than happy to replace it with this product. For people tackling this for the first time, or people with less experience. It may look intimidating at first, but take your time, and you'll be fine. There's nothing that can go back in the wrong place (all connectors are keyed). I would say for the less experienced, this should take less than an hour. I wrote this from memory, so if I missed anything, I apologize.

I installed this Dorman power window regulator in my 04 Silverado 2500 and it works great. All bolts lined up perfectly and plug right in. Couple of tips: * I used the blue painters tape to hold the window. (4 or 5 strips on both sides of the window) * to help improve the slid of the glass I also sprayed silicon on the velvet rails as well as the rubber and velvet area that actually touch the glass. I wiped the excess off on the glass areas for obvious areas. It works perfectly, and Buy Dorman if you want an easy installation.
