Anyone have a noise coming from their dash after they turn off their A/C or heat and the engine is turned off? I have a noise that sounds like a book slamming shut.
Should I be concerned? Everything runs fine otherwise...

There is a little door that directs air flow to the defroster (windshield) or to the dash vents or to the floor. If you move the selector from A/C or defrost to vent, the door will move and it can (but not always) make a soft clunk sound.
Also, you want to leave the selector switch in 'vent' when turning off the car rather than A/C or defrost. This will help to dry out the ducts so the dreaded mildew smell doesn't start.
