I have replaced the mode door actuator and completed the initiation process, and the actuator seems to be recognized by the system. However the actuator still does not respond to inputs. I have also replaced the control module and did the initiation procedure on that. Is there another part to the HVAC that would prevent the actuator from responding to inputs? Does the 05 Tahoe HVAC require to be initiated using a scan tool?
