How to replace heater/vent blend door actuator?
Blend Door/Air Temperature Actuator Assembly Replacement
- Remove the instrument panel compartment.
- Disconnect the electrical connector from the air temperature actuator assembly (2).
- Remove the air temperature actuator assembly (2) retaining screws (1).
- Remove the air temperature actuator assembly (1).
Important The passenger air temperature actuator must be properly aligned with the temperature door shafts prior to installation on the vehicle.
- Test fit the actuator to verify alignment of the cams on the replacement air temperature actuator with the temperature door shafts. If the cams and shafts are out of alignment, adjust the shafts first and proceed to cam adjustment only if necessary.
- To adjust the shafts, do the following:
- Rotate the inner and outer shafts slightly rearward. The shafts have a limited range of travel and should not be forced.
- Test fit the temperature actuator to the shafts. Be sure to align the inner shaft first.
Important The following steps will set an out range trouble code for the actuator. Be sure to erase this code when the repair is complete.
- To adjust the cams, do the following:
- Install the electrical connector to the actuator.
- Hold the actuator away from the shafts and turn the ignition to ON. The actuator will enter the automatic re-calibration mode. The cams will continue to turn until the ignition is turned to OFF.
- Observe the motion of the cams on the actuator and turn the ignition OFF when the cams are aligned with the position of the temperature door shafts.
- Test fit the temperature actuator to the shafts. If necessary, repeat the cam adjustment.
- Install the air temperature actuator assembly (1) to the HVAC module.
Caution! 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.
- Install the air temperature actuator assembly (2) retaining screws (1).
Tighten the screws (1) to 1.4 N·m (12 lb in).
- Install the electrical connector to the air temperature actuator assembly (2).
- Install the instrument panel storage compartment.
- Re-calibrate the actuators.
