System Airflow Description - Dual Automatic Temperature Control (DATC) System: Defrost

WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

When DEFROST is selected:

the recirc request button and indicator is disabled. Regardless of button and indicator status, the air inlet door actuator admits only outside air into the passenger compartment.
the floor/defrost/panel door directs airflow to the defroster duct and side window demisters. A small amount of airflow from the floor duct will be present.
blended air temperature is available.
to reduce fogging, the A/C compressor will operate automatically, regardless of indicator status.
the blower motor is ON.
