You are looking for a vacuum leak with this problem. The air flow direction is changed by vent doors. They are actuated by vacuum.
Check under the dash for vacuum leaks as well as under the hood. If you are lucky, with the engine running, you may hear a hissing noise from the leak. Check that and let me know what you find.
