If the mode door is moving too freely, it may cause excessive air flow to a particular area, but it would not cause the passenger compartment temperature to always be too hot, cold, or not changing with the temperature range. Faulty actuator, open or shorted wire, and faulty potentiometer could all cause such a problem.
