WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
When FLOOR is selected:
- The RECIRC request button is enabled. If RECIRC is selected (indicator on), the air inlet door vacuum control motor is at full vacuum, closing off outside air from entering the passenger compartment. If RECIRC is not selected (indicator off), the air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment.
- The panel/floor door vacuum control motor is at full vacuum and the panel/defrost door vacuum control motor is at no vacuum, directing airflow to the floor duct.
- The heater control valve (if equipped) is automatically controlled by the EATC module, based on the temperature settings.
- The A/C request button is enabled. When A/C is selected (indicator on), the A/C compressor will operate if the outside temperature is above approximately 6°C (43°F). When A/C is not selected (indicator off), the A/C compressor will not operate.
- The blower motor is on.
