All I can say from changing the mirror housing on my current truck is be careful - mirror glass seems very flexible until it shatters. You might check whether Silverado forums have any insight (not that it's necessarily the same on the Hummer, of course).I got the lighting package with my truck and when they installed it, my guess is they did not run the wires correctly behind it causing my side view mirror to not full function. I would like to take the glass off an play with the wires myself. This will be easier for me than taking it and having the dealer do it. Can anyone give me any suggestions on getting the glass off?
Do they just pop off like most others?
