Wondering what could be causing this. The car is parked and locked, nothing on, nothing open and it will be dinging like when the door is open with the key in ignition. It keeps dinging until after car is started. Sometimes after I start the car, the ding that it gives you to put on seat belt etc...It will do it 5 or 6 times before it stops. Anyone heard of this or had this happen. I'm thinking it may be some sort of short somewhere or perhaps a fuse?
