One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.

    A/C and Heater blows only through defrost vents; problem occurred immediately following battery replacement at Sears. Online Blogs suggest easy, relatively inexpensive fix by replacement of Mode Door Actuator; however, Hummer dealer indicated ~ $1000 repair charge for service requiring removal of entire dashboard.

    Not exactly sure if it happened when changed battery but close to that time. Air doesn't blow hard and direction varies. Air feels like it is pulsating out of vents. Dealership said it needed new door actuator behind dash. Contemplating repair. very costly.

    Once in a while the air vent shoots out very hot air! I turn off the system once or twice to resolve it!
