When DEFROST is selected:
The air inlet door is in the no vacuum position, admitting outside air.
Both the panel/defrost door and the floor/panel door are in the no vacuum position so that most of the incoming air is directed to the windshield defroster hose nozzle. There is also airflow to the A/C side window demisters.
The temperature setting will determine the amount of air that is directed through the heater core and the amount that bypasses the heater core.
The A/C compressor will be enabled when DEFROST is selected to dehumidify the air and reduce windshield fogging.
The blower motor is on

Thats what i thought, i just wanted to make sure. I just noticed the ac dripping some water this morning while i was using the defrost. I checked and say the ac was running, but my dad was insisting that it shoudnt be.
