Max A/C
WARNING: This page is about a different car, the 2007 Ford Ranger. 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, directing airflow to the instrument panel A/C registers. A small amount of airflow from the side window demisters will be present.
- The heater control valve 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).
- The blower motor is ON.
