Max A/C
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. 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 door vacuum control motor is at full vacuum and the defrost door and floor door vacuum control motors are at no vacuum, directing airflow to the instrument panel A/C registers. A small amount of airflow from the floor duct, defroster duct and side window demisters will be present.
- The heater control valve is at full vacuum when the temperature selection is in the full COOL position, preventing the flow of hot coolant to the heater core. Otherwise, blended air temperature is available.
- Air will be drawn from the recirculated air inlet by the blower motor. When the temperature selection is in the full COOL position, the airflow will be diverted past the heater core and then into the passenger compartment through the instrument panel A/C registers.
- The A/C request switch will be illuminated and will be disabled.
- The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F).
- The blower motor is on.
- The auxiliary blower motor is enabled, if equipped.
