Construction
• 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.
Operation
• The front climate control unit compares the voltage detected by the potentiometer in the front airflow actuator
with the target voltage.
• Operates the motor in the front airflow actuator until the detected voltage and the target voltage are equal.
