Airflow Mode Door Position:
The airflow mode door actuator uses a cam and lever assembly to position the airflow mode doors on command from the HVAC module.
The mode door actuator contains a reversible electric motor and potentiometer. The potentiometer circuit reports the position of the airflow mode doors to the HVAC module. The HVAC module drives the actuator motor in whichever direction is necessary to move the airflow mode doors to the position set by the vehicle occupants using the mode selector buttons.
The airflow mode door actuator is mounted to the plenum chamber to the right of and above the accelerator pedal and can be installed separately.
