I have a serious issue with my power windows in my 99 grand prix gt 4 door. The windows will work fine for two or three weeks, then suddenly will not roll up or down using any switch in the car. This will last for a few hours or even a few days. Then just as suddenly the windows will begin working again. It happens very regularly and is inconvenient to say the least. Tonight I had to put trash bags over my windows because the windows would not roll up and we had a rain storm. Please help!!
