Air Speed: Off

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

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 blower and A/C requests will be cancelled and the A/C request LED will turn off. 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. The recirculation mode will stay on until either fresh air is selected. The HVAC control module will stay in recirculation mode for 30 minutes after the ignition switch has been turned off.
