My 83 928 only blows through the defroster vents....how can I fix this???

No matter what setting I put the climate control on, it only blows through the defroster vents. I read somewhere that a "door" maybe stuck.. Can someone advise me as to what I can do? (83 928S)

The system uses vacuum actuators which stop working when the rubber diaphragm goes bad. Talk to Roger at 928sRus for replacement parts.

Also make sure the vacuum system is working, no vacuum is defrost.
