there is an electric motor which controls the recirculation door. inside the little black box-motor is plastic gears. it sounds like you may have something blocking the door & that took out the gears. either way you need to replace the motor & manually operate door to check for obstructions. just make sure there are no children around as you are going to swear alot doing the motor job. I suggest removing the heater box assy.
