Recirculation Mode

When recirculated air switch is pressed, the A/C-heater control module commands actuator to close air inlet door to outside air. Recirculation mode is available in panel/floor, panel and floor modes. Recirculation mode is not allowed in front defrost or floor/windshield modes because windshield fogging might occur.
