Removal & Installation

Print


CAUTION
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 negative battery (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 and possible personal injury or death.


NOTE
The single zone heater-A/C 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.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Disconnect and isolate the negative battery cable.
  4.  
  5. Remove the silencer from beneath the driver side end of the instrument panel.
  6.  
  7. Disconnect the wire harness connector from the blend door actuator being serviced.
  8.  
  9. Remove the two screws that secure the blend door actuator being serviced to the air distribution housing and remove the actuator.
  10.  

To install:

  1. Position the blend door actuator being serviced onto the air distribution housing. If necessary, rotate the actuator slightly to align the splines on the actuator output shaft with those in the blend air door linkage.
  2.  
  3. Install the two screws that secure the blend door actuator being serviced to the air distribution housing. Tighten the screws to 17 inch lbs. (2 Nm).
  4.  
  5. Connect the wire harness connector to the blend door actuator being serviced .
  6.  
  7. Install the silencer under the driver side end of the instrument panel.
  8.  
  9. Reconnect the negative battery cable and calibrate the A/C heater control as follows:
    1. Turn the ignition switch to the ON position.
    2.  
    3. If equipped with the manual temperature control system, press and hold the Rear Wipe/Wash and Recirculation buttons for at least five seconds. If equipped with the automatic temperature control system, simultaneously press and hold the Power and Recirculation buttons on the A/C-heater control for at least five seconds. The manual A/C heater control Rear Wipe/Wash button light and Recirculation button light, or the automatic A/C heater control Delay and Recirculation graphics will begin to flash when the calibration procedure has begun.
    4.  
    5. The calibration procedure should take less than two minutes to complete for the manual A/C heater control, and less than twenty seconds for the automatic A/C heater control. When the lights or graphics stop flashing, the calibration procedure is complete.
    6.  
    7. If the lights or graphics continue to flash beyond the two minute (manual) or twenty second (automatic) calibration time, it indicates that the A/C heater control has detected a failure and a Diagnostic Trouble Code (DTC) has been set. The lights or graphics will continue to flash even after the ignition switch is cycled off and on, until a successful calibration is completed or until the vehicle has been driven about 8 miles (13 km).
