Operation CHARM: Car repair manuals for everyone.

Off Mode

When the vehicle is moving, air flowing over the vehicle increases the air pressure just ahead of the windshield. This forces air into the ambient air inlet, into the HVAC module and out through the floor outlets. The HVAC control processor attempts to match the inside air temperature and driver selected temperatures. Since the A/C compressor is not running, the incoming air may be warmed but not cooled. Press the OFF switch to turn off the HVAC system. The ambient air temperature will show on the VF display at all times. The HVAC control module will return to the previous driver settings, except for manual RECIRCULATION and FRONT DEFROST.
