well first i need to know what kind of car
Reply:ive had that problem in numerous old cadillacs, and i was always told that it was a vacuum leak.
Reply:This is the fail safe mode that happens when there is no vacuum to the unit.


There may be a vacuum hose off under the hood.


Without knowing any more about the make of car, this is all I can help with.
Reply:B from B is right. Not sure what kind of car you have, but a vacum leak will keep the vent doors from operating. They do it in my Jeep all the time.
