there are alot of posts on here about peples alarms just randomly going off, mine does this. It is not the shock sensor because there arnt any loud vehicles going by or cats jumping on my car. There was a gm mechanic that got on this site about a year ago and mentioned that 8 out of ten grand prix have this problem and that is the door trigger switches being bad that causes it. however he said what to do to them but not where they were located.............ggggggggggggrrrrrrrrrrrrr please help!
