Controls and Compressor Cycling: Defrost

WARNING: This page is about a different car, the 2013 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

When DEFROST is selected:

the recirculated air request button is disabled. The air inlet door opens, allowing only outside air into the passenger compartment.
the mode doors direct airflow to the defroster duct and side window demisters. A small amount of airflow from the floor duct is present.
the A/C is turned on in defrost. The Air Conditioning (A/C) compressor operates as long as the outside temperature is above approximately 6 C (43 F).
blended air temperature is available.
the blower motor is on and the speed is adjustable.
