Temperature Actuator Replacement LH

Removal Procedure

  1. Remove the left instrument panel insulator. Refer to Instrument Panel Insulator Replacement in Instrument Panel, Gauges and Console.
  2. Remove the knee bolster. Refer to Knee Bolster Replacement in Instrument Panel, Gauges and Console.

  3. Object Number: 295297  Size: SH
  4. Disconnect the electrical connector from the temperature valve electric actuator.
  5. Remove the mounting bolts from the temperature valve electric actuator.

  6. Object Number: 295301  Size: SH
  7. Remove the temperature valve electric actuator.

Installation Procedure


    Object Number: 295301  Size: SH
  1. Position the temperature valve electric actuator, then align the slots in the electric actuator driver to the flats on the temperature valve shaft.
  2. Slide the electric actuator driver onto the shaft, while aligning the actuator locating hole to the forward alignment pin on the HVAC control module case. The actuator driver should completely seat onto the temperature valve shaft and the mounting holes should be flush with the mounting bosses on the HVAC control module case.
  3. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  4. Install the mounting screws to the temperature valve electric actuator.
  5. Tighten
    Tighten the temperature actuator bolts to 1.5 N·m (13 lb in).


    Object Number: 295297  Size: SH
  6. Connect the electrical connector to the temperature valve electric actuator.
  7. Install the knee bolster. Refer to Knee Bolster Replacement in Instrument Panel, Gauges and Console.
  8. Install the left instrument panel insulator. Refer to Instrument Panel Insulator Replacement in Instrument Panel, Gauges and Console.
