My 96 Z-28 Had the driverside window motor burn up. I replaced it at over $400 Installed . Now the passenger side window will not oporate and driver side is starting the start stop problems the other two showed before completely failing. My sister replaced her passenger window motor (1995 Trans-Am)over a year ago! What gives(or dont give) with these Power window motors ?
Have you cleaned the switch? try taking the switch apart and actually scrping and sanding the "goo" off of them. I say this, because alot of window problems are dirty switches. It's worth a try and free, so if it doesn't work, then look into new motors.-JOE-
