Front Defrost Mode

When FRONT DEFROST is selected, the A/C compressor is activated. Outside air is brought into the vehicle. Air is directed toward the windshield with a small amount of air toward the floor and side window outlets. Vacuum is supplied to both sides of the mode actuator and one side of the defrost actuator. The defrost actuator retracts, opening the defroster door and holding the mode door stationary. The rear window defogger does not affect the HVAC system at all.
