Removal & Installation

NOTE
Cost, personal injury or death, environmental damage, and legal considerations (such as the fact that it is a federal crime to vent refrigerant into the atmosphere), dictate that this component on your vehicle should be serviced only by a Motor Vehicle Air Conditioning (MVAC) trained, and EPA certified automotive technician. This operation involves removal of the entire HVAC (Heating, Ventilation, Air Conditioning) Module.


NOTE
The blend door actuator cannot be adjusted or repaired and, if damaged or faulty, must be replaced. After installation the new actuator must be calibrated using a scan tool.

  1. Disconnect and isolate the negative battery cable.
  2.  
  3. Remove the instrument panel assembly.
  4.  
  5. Remove the screws that secure the blend door actuator to the top of the HVAC housing.
