•  Opens/closes the air mix door based on the signals from the front climate control unit to adjust the temperature.

•  A potentiometer type, which allows minute and smooth changes of the door position, has been adopted.

•  The front climate control unit compares the voltage detected by the potentiometer in the rear air mix actuator with the target voltage.

•  Operates the motor in the rear air mix actuator until the detected voltage and the target voltage are equal.
