Heard loud banging from my parked Explorer when i got up.
Went to see what was going on, thought a squirrel had got in couldn't get out.
Opened the door and nothing anywhere, but Explorer was making banging sound coming from the body of vehicle.
Removed battery cable and noise stopped...never had that happen before.
It was a loud bang, not a click or something...the vehicle had been parked overnight.
Anyone have an idea what this loud noise could be....thanks in advance

Sometimes the flaps for the air/heat direction will break and not realize they are supposed to be hitting a "stop" and just keep running.
