Airflow control servo quit working. Could only get cold air from flipping the control knob to defrost, Couldn't get any cold air out of the front vents. Made for tough driving on hot, humid nights. Windshield wanted to fog over. Made a simple redneck solution and put a cover over the defrost vent to blow the air out to me and keep it off the windshield. It helps but having the flow control working proper like it's supposed to would be way more convenient!
