well ive got an 06 g6 3.5 v6, and my ac compressor is locked up. i was at a red light when all of a sudden the car jerked hard as if someone had hit me from the back. i turned off the ac and evrything was ok but when it started feling hot i turned on the ac and the damn compressor was locked. i bought the car cpo so the waranty was good up 39k mile. the car at that time had 40k. i still took to dealer and sure enough they said "oh we cant help you are out of waranty". so i was pissed cause thats way too soon for the comp to go out. has this happened to anyone else? or are there any suggestions? the car now has 51k so fighting with dealer is out of the question. please help cause its hotter than Hell!
