It sounds like you may have hit the problem. The vent doors are actuated by vacuum. Chances are you either have a stuck door or a vacuum leak (which is most likely). Check under the dash for leaks. With the engine running you may get lucky and hear a hissing sound from the leak.

Let me know what you find.
