I have a 2010 Challenger RT 6 speed. I have noticed on several different makes when you open the door after the car has sat a while that some sort of sound like a vent is opening or closing. When I opened my door today something was going on cause a loud clicking sound started and it is coming from behind the dashboard. It has done it three more times today. It only does it after the car has sat a bit. Anyone know what this is or what the fix could be?
