I'm new to the forum, so I hope I can ask ?'s here. I have a 2004 MC SS Super Charged. My car has become possessed. It's intermittent but frustrating. Out of the blue my cars door locks will lock & unlock, My warning gauge lights up w/Door Ajar, Change Oil, etc. all while I'm driving. The door locking & unlocking is headache forming alone. Than when I shut car off the dome light stays on. Give it some time and the Horn starts blaring. I undo the positive side of the battery as to not freak out the neighbors. My battery as well as my alternator test out great! Someone mentioned it could be my Body Control Module...is someone out there that has experienced my nightmare? If so please enlighten me. Thx! Gary
