In my 86 Deville, the vents dont blow the air out. I can feel heat or cold air when the a/c is on. Also when i switch from the auto to defrost, i can hear the flaps switching, but the air isnt being blown out. It is mainly a problem when i need to defrost the windshield. I dont know if it's a fan that is broken or a switch. A friend of mine said it may be a vacum line? Any ideas why air isnt blowing out?
