The air temperature actuator is located on the top right hand side of the heater/vent module.

1. Remove the instrument panel carrier. Refer to Instrument Panel Carrier Replacement in Instrument Panel, Gauges, and Console.



2. Disconnect the electrical connector (2).



3. Remove the air temperature actuator retaining screws.
4. Remove the air temperature actuator from the heater/vent module.

1. Install the air temperature actuator to the heater/vent module. Ensure that the actuator is seated on the locating tab.

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.

2. Install the air temperature actuator retaining screws.
