probably a vacuum leak check all the rubber hoses about 1/4 inch in diameter and hard plastic hoses about 1/8 inch the hoses that go to the vacuum switch that works your heater/ac vents is also prone to leak turn selctor to max then norm then defrost and listen for a spewing sound you should hear it for a second or two each time you move the selector knob if the spewing continues it is leaking
