Off Mode

When the OFF position is selected, the HVAC control module applies voltage to the blower switch off input within the HVAC control module through the off blower motor control circuit. When the HVAC control module receives this input; any A/C request will be cancelled and the A/C request LED will turnoff. Fresh air will still be brought from the outside, but the LED indicator will not illuminate. The temperature and mode controls will continue to function only to manipulate the fresh air that enters the vehicle. The recirculation function can still be activated and the LED will illuminate. The recirculation mode will stay on until either fresh air is selected or the next key-on ignition cycle.
