I have one rear power window out of commission. There is power to the switch, and I tried to bypass the switch, so I assume the motor is done. In the mean time, I have one roof rail weatherstrip done, and I'd like to do the other, but the window is in the way. Any suggestions on how I could lower it a couple of inches, install seal, then put it back until I get whats needed to fix it? Or anything else I could try to diagnose? tks!
