If you have an 04 Envoy, and your rear window won't go up, this might be your fix. If the window is sliding down into the gate, the gate will not work in any position because the computer doesn't know the status of the window. In any case, we are having this problem, and last year we had a similar problem with the MID GATE (we have the XUV). It was a bad regulator - the plastic on the cable had broken and the window dropped and would not go up. Well, anyways, I just got a call from my wife, and the rear gate is doing the same thing now. She put some items in the back storage area and closed the gate (side hinge, glass up), and not long thereafter, the window started sliding down and would not go up.

The two assemblies involved are the REGULATOR and the Window MOTOR. The motor apparently does not fail that often, so they have separated the two items.

and the PRICE is very right. The Dealer will charge you probably 2-3 times as much for this part.

And the motor, if needed:

Hi. I have a 2005 envoy xuv slt. And I have both the same problems. Midgate window and tailgate window as well. Both will not go up either. Also I checked both Amazon links for each part and it says it will not fit my vehicle that I have linked to my Amazon. Weird! Now in my Midgate window, the front switch when pressed, you can hear it trying to work. As for the tailgate window switch, when pressed you don't hear nothing. Any advice would help please. I've had it with this vehicle. Just got done with a bunch of overheating and fan clutch problems. Still gets hot, but only when radio or back port is being used!
