•  Opens/closes the mode door based on the signals from the front climate control unit to switch the air vents.

•  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 airflow actuator with the target voltage.

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