Climate Control System: Heating/Ventilation
WARNING: This page is about a different car, the 2004 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
Coolant flows through the heater core constantly. The heating capacity is controlled by means of a mechanical air temperature valve.
All vehicles have a recirculated air function, with the flap controlled by a servo motor. If the recirculated air function is selected, it remains active even when the ignition is switched on or off. For additional information, refer to HEATING & VENTILATION .
