WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

When FLOOR/DEFROST is selected:

The air inlet blend door is in the no vacuum position, blocking recirculated air and allowing outside air.
The footwell blend door is at full vacuum allowing air to flow through the footwell ducts.

The vent/register blend door is at no vacuum.
The A/C compressor is enabled to dehumidify the air and reduce windshield fogging.
The blower motor is on.
