- Remove the four screws that secure the rear blower motor housing to the floor console base and duct assembly.
- Remove the rear blower motor housing and place it on a bench.
- Disconnect the rear blower motor wire harness connector from the power module.
- Remove the eleven retaining clips and three screws that secure the housing together.
- Carefully separate the two halves of the housing.
Remove the blower motor wire harness and grommet from the housing and remove the blower motor.
- Position the rear blower motor into the housing and install the blower motor wire harness and grommet.
- Assemble the two halves of the rear blower motor housing and install the eleven retaining clips and three screws. Tighten the screws to 17 inch lbs. (2 Nm).
- Connect the rear blower motor wire harness connector to the rear blower motor power module.
- Position the rear blower motor housing into the floor console.
- Install the four screws that secure the rear blower motor housing to the floor console base. Tighten the screws to 17 inch lbs. (2 Nm).

Perform the heater-A/C control calibration procedure, as follows:
NOTEThe A/C-heater control module must be recalibrated each time an actuator motor or the A/C-heater control is replaced. If the vehicle is so equipped, the calibration procedure also includes rear HVAC positions for each actuator motor.
- Turn the ignition switch to the ON position.
- If equipped with the Manual Temperature Control (MTC) system, press and hold the Power and Recirculation buttons for at least five seconds. If equipped with the automatic temperature control (ATC) system, simultaneously press and hold the Power and Recirculation buttons on the A/C-heater control for at least five seconds. The MTC A/C-heater control Power button light emitting diode (LED) and Recirculation button LED, or the ATC A/C-heater control Delay and Recirculation graphics will begin to flash when the calibration procedure has begun.
- The calibration procedure should take less than two minutes to complete for the manual A/C-heater control, and less than twenty seconds for the ATC A/C-heater control. When the LEDs or graphics stop flashing, the calibration procedure is complete.
- If the LEDs or graphics continue to flash beyond the two minute (manual) or twenty second (ATC) calibration time, it indicates that the A/C-heater control has detected a failure and a Diagnostic Trouble Code (DTC) has been set. The LEDs or graphics will continue to flash even after the ignition switch is cycled Off and On, until a successful calibration is completed or until the vehicle has been driven about 8 miles (13 km).
