System Airflow Description - Manual Climate Control: Floor/Defrost
WARNING: This page is about a different car, the 2004 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
When FLOOR/DEFROST is selected:
- 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 partial vacuum and the panel/defrost 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 side window demisters will be present.
- The heater control valve is at no vacuum allowing the flow of hot coolant to the heater core. Blended air temperature is available.
- The temperature can be adjusted to heat or cool the air below the outside temperature.
- The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F).
- The blower motor is on.
