System Airflow Description - Electronic Automatic Temperature Control: Floor/Defrost
WARNING: This page is about a different car, the 2005 Mercury Sable and 2005 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
When FLOOR/DEFROST is selected:
- The recirc request button is enabled. If the recirc request button is selected (indicator on), the air inlet door actuator closes off outside air from entering the passenger compartment. If the recirc request button is not selected (indicator off), the air inlet door actuator admits only outside air into the passenger compartment.
- The panel/floor door vacuum control motor is at partial vacuum and the defrost door 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 request button will always toggle the indicator and will only operate the A/C compressor when the recirc button is in fresh air mode and the outside temperature is above approximately 6°C (43°F).
- The blower motor is on.
