Front Defrost Mode

When FRONT DEFROST is selected, the A/C compressor is activated and outside air is brought into the vehicle. Air will be directed toward the windshield with a small amount of air toward the side window outlets. Vacuum is supplied to both the yellow and brown actuators. Recirculation mode is not available in front defrost. The rear window defogger and heated outside mirrors do not affect the HVAC system at all.
