    Check for any broken vacume lines that supply vacume to HVAC controls. Vacume is supplied from engine intake manifold.

    Sounds like selector switch not switching, will it switch from vent to floor and back? Anything fallen into defrost vent? Check ebay for control panel at a good price, if needed. No vacuum defalt should be defrost!
