1998 Grand Prix GT 2Door, when the car is running or in the on position and i open the door i get the door chime maybe 2 times and the radio and chime stop for about 3 second and radio comes back on and no chime... i think the chime is just letting me know the door got opened, and it only happens about 80-90% of the time when i open the door, anybody have a clue what gremlin is messing with my car now? PLEASE HELP
