Question about 1993 Buick LeSabre
When i turn on the front defroster the air comes out of the vent
The door that changes position in your ductwork to direct airflow is not functioning properly. There is an actuator that operates off vacuum that makes the door open and close. The most common cause of this condition is a vacuum leak. Check all the vacuum hoses and make sure they are properly connected and are not brittle and cracked.
