Actuators

There are five actuators used to control the HVAC system. They are driver and passenger mix door actuators, A/C door actuator, defroster actuator, and air inlet actuator. The actuators are specifically designed for the right and left side of the HVAC module. When servicing an actuator, be sure to replace it with the correct replacement actuator for the position being serviced.

A reversible DC motor in the actuator operates the valve within the HVAC module. The actuators contain a feedback potentiometer that informs the heater and A/C programmer of valve position.
