Hello fellow Grand Prix lovers. I was wondering if anyone else has had a solution to my problem. I own a 99 Grand Prix GTP. The compressor was replaced a year ago and my A/C is super cold. One day the car was sitting while running with the A/C on and the compressor just cut off and would not come on again. Since I'm in Florida where A/C is a must I hightailed it home. After turning the car back on the A/C worked fine again. Later that week it did the same thing when I was sitting at the bank. This time I turned off the air and tried it a few minutes later while going down the road. It worked fine and didn't give me any more trouble. THe other day I was driving down the road and the A/C just shut down. Same thing happened. I waited awhile then tried it and it worked fine again. I swapped out the A/C relay in the fuse box with an identical one that was used for something else but this had no effect. I just wondered if anyone knew if there is a sensor or connector somewhere that has problems with intermittent results. Any help would be greatly appreciated.
