Climate Control System - System Operation and Component Description: Floor/Defrost

WARNING: This page is about a different car, the 2019 Lincoln Nautilus. However, it is still accessible from the selected car via links, so may be relevant.

When FLOOR/DEFROST mode is selected:

the recirculated air request button is enabled. If the recirculated air request button is selected (indicator on), the air inlet door closes, preventing outside air from entering the passenger compartment. If the recirculated air request button is not selected (indicator off), the air inlet door opens, allowing only outside air into the passenger compartment.
the air distribution doors operate in combination to direct airflow to the floor duct, the defroster duct and the side window demisters.
blended air temperature is available. Only when A/C compressor operation has been selected by pressing the A/C button (indicator on) can the airflow temperature be cooled below the outside air temperature.
the blower motor is on and the speed is adjustable.
