I have a 97 Grand Prix SE, I had this problem a while back that stopped, now after replacing the blower motor for the heater it's BACK and it's driving me bonkers!! It's the chime that will go off if you open the door with the key on (3 or 4 dings) If I swerve the car hard left/right, it does not go off, if I break hard, accelerate hard, no chime, a hard bump (rough road) on one side only, no chime. If I go over a fairly gradual bump (dip in the road) chime goes off, rough road on both side, chime goes off. When I first put the car in gear and drive out of the garage (no bumps) it goes off after about 20'. I have jiggled wires under the dash, bounced the front end up and down and I can not get it to chime when sitting still.... I am at my wits end trying to figure out what is doing this. At times it will chime repeatedly, and the stereo will turn off and on....I'm about ready to find the chime/dinger and just cut the wire, but I'd rather try to find the cause rather than do a redneck fix... :P
thanks
