1990 Pontiac Firebird ProblemsWindows Rattling and Scraping
The windows on the 1984-2002 Pontiac Firebird and Trans Am commonly lean in towards the cabin when they are rolled down, and a metal-on-glass rattle is heard with any vibration. As the problem advances, popping may be heard from the door as the window rolls up or down.
This issue is caused by failing window regulator rivets which no longer hold the window upright. This places undue strain on pads that prevent the window from contacting the metal door frame. After a short time, the pads inside the door wear out, allowing the window to rattle and become scratched in a vertical pattern.
To correct the rattling and popping noises, the window regulator rivets and pads must be replaced.
The roller on the window guide attached to the bottom of the window glass may break off and cause the window to come off track.
The fuel injectors may short out electricity causing a rougher than normal idle.
