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 instrument panel driver knee bolster bracket. Refer to Knee Bolster Bracket Replacement in Instrument Panel Gauges and Console.
  3. Disconnect the electrical connector at the temperature valve electric actuator.

  4. Object Number: 417391  Size: SH
  5. Remove the bolts that secure the temperature valve electric actuator to the HVAC module.
  6. Remove the actuator from the vehicle.

Installation Procedure


    Object Number: 417391  Size: SH
  1. Install the temperature valve electric actuator.
  2. Position the temperature valve electric actuator, then align the slots in the electric actuator driver to the flats on the temperature valve shaft.
  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 bolts.
  5. Tighten
    Tighten the temperature actuator bolts to 1.5 N·m (13 lb in).

  6. Connect the electrical connector at the temperature valve electric actuator.
  7. Install the instrument panel driver knee bolster bracket. Refer to Knee Bolster Bracket Replacement in Instrument Panel Gauges and Console.
  8. Install the left side instrument panel insulator. Refer to Instrument Panel Insulator Replacement in Instrument Panel Gauges and Console.
