System Airflow Description - Electronic Automatic Temperature Control: Floor/Defrost
WARNING: This page is about a different car, the 2003 Mercury Sable and 2003 Ford Taurus. 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 defrost door and floor console duct door (if equipped) vacuum control motors are at no vacuum, directing airflow to the floor duct, the defroster duct and the side window demisters.
- 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.
