USUALLY A VACUUM LEAK, CAUSES THE AIR TO BLOW THRU THE DEFROSTER VENTS. IF THIS IS TRUE. CHECK THE VACUUM LINES UNDER THE HOOD (USUALLY THIN BLACK PLASTIC OR RUBBER) AND WHERE THEY CONNECT TO THE HVAC CONTROLLER IN THE DASH. LISTEN FOR THE LEAK WHILE THE ENGINE IS IDLING. IF NOT, COULD BE DAMPER DOOR MOTOR STUCK OR INOP. GOOD LUCK!
