Which model do you have, the rear-wheel-drive Fifth Ave. Or the front-wheel-drive K-Car?

Both use vacuum motors to run the actuators on the heater box but the temperature door is run with a cable and lever, unless you have automatic temperature control on the front-wheel-drive model. For that, a failure in the controller is much more common than a failed actuator.
