SYMPTOM/CONDITION:
Some customers may experience an intermittent condition where air flow from the HVAC vents is noticeable while driving with the HVAC system off.
This may be more noticeable with the temperature settings at medium or higher heat settings due to the temperature differential coming out of the ducts.
Turning the blower on, and then off will force the fresh air/recirculation door closed eliminating the airflow.
DIAGNOSIS:
Using a Scan Tool (StarSCAN(R)) using the appropriate Diagnostic Procedures available in TechCONNECT, verify all A/C Systems are functioning as
designed. If DTC's are present record them on a repair order and repair as necessary before proceeding further with this bulletin. If the
Symptom/Condition is experienced or described by the customer, perform the Repair Procedure.
