Actuator Replacement
WARNING: This page is about a different car, the 2006 Chevrolet Monte Carlo and 2006 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
If an actuator is replaced, a Re-Calibration of the actuator is not necessary. The HVAC module knows the exact location of the door when the HVAC system is turned on.
