Actuators

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

A reversible DC motor in the actuator operates the door within the HVAC module.

The actuators contain a feedback potentiometer that informs the HVAC programmer of door position.
