DESCRIPTION

The blend door actuators are reversible, 12-volt Direct Current (DC), servo motors. Models with the single zone heater and air conditioner system have a single blend door, which is controlled by a single blend door actuator. Models with the optional dual zone front heater and air conditioner system have dual blend doors, which are controlled by two blend door actuators. The single zone blend door actuator is located on the driver side end of the HVAC housing, close to the dash panel. In the dual zone system, the same blend door actuator used for the single zone system becomes the driver side blend door actuator, and is mechanically connected to only the driver side blend door. In the dual zone system, a second separate blend door actuator is also located on the top of the HVAC housing and is mechanically connected to only the passenger side blend door.

The blend door actuators are interchangeable with each other, as well as with the actuators for the mode door, defrost door and the recirculation door. Each actuator is contained within an identical black molded plastic housing with an integral wire connector receptacle. Integral mounting tabs allow the actuator to be secured with three screws to the HVAC housing. Each actuator also has an identical output shaft with splines that connects it to the linkage that drives the proper door. The blend door actuators do not require mechanical indexing to the blend door linkage, as they are electronically calibrated by the heater-A/C control module. The blend door actuators cannot be adjusted or repaired and, if damaged or faulty, they must be replaced.

REMOVAL

WARNING:On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in accidental airbag deployment, possible personal injury or death.

NOTE:The single zone heating and air conditioning system is equipped with a single blend door actuator. The dual zone system has two blend door actuators, one for the driver side blend air door and one for the passenger side blend air door. The same service procedures can be used for each of these actuators.

  1. Disconnect and isolate the battery negative cable.
  2. Remove the instrument panel from the vehicle
  3. Disconnect the wire harness connector from the blend door actuator(s)
