When MAX A/C is selected:

  • The recirculation air duct door is at full vacuum, closing off outside air and admitting only recirculated air.
  • The floor/panel door and the floor/defrost door are at the full vacuum position, directing airflow to the A/C register.
  • The temperature is usually set for maximum cold but may be heated if desired.
  • Air will be picked up at the recirculation opening by the blower motor. With the A/C control set for maximum cold, airflow across the evaporator core will be diverted past the heater core and then directed into the passenger compartment through the instrument panel A/C register. There is also some airflow to the side window demisters.
  • The A/C compressor will be enabled when MAX A/C is selected.
  • The blower motor is ON.
