WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
When MAX A/C is selected:
- The air inlet door vacuum control motor is at full vacuum, closing off outside air and admitting only recirculated air.
- The panel/defrost door vacuum control motor is at full vacuum and the panel/floor door vacuum control motor is at no vacuum position, directing airflow to the instrument panel A/C registers.
- The heater control valve (if equipped) is at full vacuum, preventing the flow of hot coolant to the heater core. Blended air temperature is not available.
- The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F).
