Problem Reported: Heater Stuck on Hottest Setting Due to Broken Heater Blend Door
May 27, 2010, 11:08 AM

A failed heater blend door or actuator can cause the temperature control for the HVAC system to stop working. A clicking sound from the dash area would commonly indicate an actuator fault. If the heater gets stuck on the hottest setting, the heater blend door may be broken requiring replacement of the heater box to repair the issue.
