Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Recirculation Operation
The HVAC control module controls the air intake through the recirculation actuator. Recirculation is only available when the HVAC control module is in Vent or Bi-level. The operator must activate the blower for Recirculation operation. When the recirculation actuator sees an open in the control circuit, the actuator will default to the recirculation position.
