Affected Component: EQUIPMENT:APPLIANCE:AIR CONDITIONER

Summary

Some customer's may complain that the HVAC system only blows warm to cool air (not cold) after starting the vehicle and not moving right away. This may be caused by a closed Active Air Shutter (AAS). Under specific circumstances, the AAS has a “learning issue” where AAS is kept closed after startup even if the PCM requests it to be open. The shutters will open and work correctly as soon as the vehicle speed exceeds 6.25 MPH (10 KPH). NO DTC will be set when this happens.
