When MAX A/C is selected:

• The air inlet blend door is at full vacuum, closing off outside air and allowing only recirculated air.
• The defrost blend door is at full vacuum while the footwell blend door is at no vacuum, closing both doors.
• The vent/register blend door is at partial vacuum, directing airflow to the driver-side, passenger-side and center registers.
• Temperature control is usually set for maximum cold but may be heated if selected.
• Air is picked up at the recirculation opening by the blower motor. With the temperature control set for maximum cold, air flows across the A/C evaporator core, diverting past the heater core and then directed into the passenger compartment through the driver-side, passenger-side and center registers.
• The A/C compressor is enabled when MAX A/C is selected.
• The blower motor is on.
