Off Mode
WARNING: This page is about a different car, the 2003 Pontiac Sunfire and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
When the OFF position is selected, the HVAC control assembly applies ground to the blower switch off input within the HVAC control assembly through the off blower motor control circuit. When the HVAC control assembly receives this input, any A/C request will be cancelled and the A/C request LED will turn off. The recirculation operation can function with blower motor in the OFF position.
