Air Door Actuator / Motor: Description and Operation
The HVAC system uses four actuators to adjust temperature and air distribution.
The actuators are:
^
The driver air mix actuator.
^
The passenger mix actuator.
^
The mode actuator.
^
The air inlet actuator.
The actuators are specifically designed for the right and left side of the heater and the A/C module. When servicing the actuator, ensure that you replace
the actuator with the correct service part for the position being serviced.
The reversible DC motor in the actuator operates the valve within the HVAC module.
The actuators contain a feedback potentiometer that informs the instrument panel module of the valve position.
