When I turn on the heater or switch from a/c to heat there is a banging noise coming from under the dash. It seems like the "door" that needs to open or close to allow the heat to come on is getting stuck. The banging seems to be the door trying to switch from a/c to heat is flapping. Could that be?
have the same problem?
