Having Power Window Issues With 1999 Pontiac Grand Am?

[Dingo444]

Hi everyone! I have a 1999 Pontiac Grand Am With Power Window Issues? My Grand Am is a great car, does not eat up too much fuel, and only has 105K miles on it. The problem exists with the power windows, specifically the back power windows. A couple of weeks ago they started refusing to go up when I or someone in the backseat hit the windows up button. We pulled the window up by hand and tried them again, and same thing occurred. So to sum up, they roll down fine like good little windows, but refuse to roll up, like evil little windows. Since the problem happens to both backseat windows on opposite sides of the car, I'm thinking it might have to do with a wiring problem, maybe at a spliced location a wire has gone bad. The fuse inside the car has been checked and is good. I hope some of you fabulous geniuses out there can help my wife and me solve this, 'cause it's driving us nuts! Any help would be greatly appreciated. One more thing, I'm fairly good at crawling around cars and under engines, and could certainly engage in a do-it-yourself process, but solving the equation is no doubt way above my pay scale. Any help would be most welcome! Thanks

Sounds like you are going to have to invest in a Haynes or Clymer manual and strip a door down to see what's going on. It may be corrosion due to water ingress or something a can of WD40 will sort out but you won't know till you look. My guess would be it's mechanical and not electrical.

GM cars are notorious for there window switch assemblies going bad. Even though it is only your rear windows that are messed up it is most likely your front driver side unit that needs replacing
