Rear Climate Control

The rear climate control system has the following features:

• The rear climate control system is functional whenever the front HVAC control module is in any mode.
• The rear blower motor recirculates the air inside the vehicle, outside air is not  available to the rear system.
• Air is cooled and dehumidified by the rear A/C evaporator core only if the front (main) climate control system is operating in a mode that requires A/C compressor operation.
• The rear air distribution doors are controlled by electric actuator motors.
• The rear climate control system has 2 rotary switches; one switch controls the blower motor speed and the other switch controls both temperature and airflow. Both rotary switches are located on the rear of the front floor console. Temperature and airflow are controlled together using the same rotary switch. When the temperature is set to full warm, the airflow discharges from the registers located in the rear of the B-pillar trim panels in front of the 2nd row seats. When the temperature is set to full cool, the airflow continues to discharge from the registers located in the rear of the B-pillar trim panels in front of the 2nd row seats and from the panel registers at the beltline in front of the 3rd row seats. A temperature setting between cold and hot results in a mixed airflow from all rear registers.
• The rear climate control system uses an electric booster heater to warm the air inside the vehicle (no heater core). For more information on the electric booster heater, Refer to: Supplemental Climate Control - System Operation and Component Description .
