Hi got same problem, when for service one front bushing at the dealer, whent to get my car and the driver side window did not work. I found the problem, I wire whas cut (probably the dealer cut it ). They cut the wire in the harness that you see when the doo is fully open, there is a rubber over the wires so you dont see them, slide it off, and look for a cut cable. I solder and tape the wire and working good ever since. Will never buy a GM product ever again, still waiting for a head light assy and a seat cover since march 2009. Hope this helps!
