HVAC actuator replacement on a 2004 GMC envoy SLT with Automatic climate control. After replacing the Blower control module this GMC envoy would only blow air out of the defrost vent, a telltale sign of a faulty Mode door actuator. I show you how to replace an HVAC actuator and Perform an HVAC module recalibration.
