Operation - HVAC System Airflow
WARNING: This page is about a different car, the 2003 Dodge Intrepid, 2003 Chrysler Intrepid, 2003 Chrysler Concorde, and 2003 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
Airflow temperature can be adjusted by the blend door with the TEMP control on the a/c heater control. After the air passes the blend door, the air flow is then directed from the PANEL, BI-LEVEL (panel and floor), and FLOOR-DEFROST outlets. Air flow velocity can be adjusted with the blower speed selector switch on the a/c heater control.
Ambient air intake can be shut off by closing the recirculation door. This will recirculate the air that is already inside the vehicle. See owners manual for recirculation operation.
