System Airflow Description - Manual Climate Control: Floor/Defrost
WARNING: This page is about a different car, the 2003 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
When the FLOOR/DEFROST is selected:
- The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment.
- The floor/defrost door vacuum control motor is at partial vacuum and the panel door vacuum control motor is at no vacuum, directing airflow to the floor duct, the defroster duct and the side window demisters. A small amount of airflow from the instrument panel A/C registers will be present.
- Blended air temperature is available.
- The A/C request button will not illuminate and is disabled. To reduce fogging, the A/C compressor will operate automatically if the outside temperature is above approximately 2°C (35°F).
- The blower motor is on.
- The auxiliary blower motor is enabled, if equipped.
