The problem is with the blower door actuator. It's vacuum driven and controls the air flow from the defrosters, vents, and floor. With the AC on, open the hood and check the lines (very skinny rubber lines) at the firewall in front of the passenger and work back ward. You're looking/listening for a vacuum leak, either a pinhole or maybe a worn end in need of repair.
