When DEFROST is selected:

• The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment.
• The panel/floor door and floor/defrost door vacuum control motors are at no vacuum, directing airflow to the defroster duct and the side window demisters.
• The temperature can be adjusted to heat or cool the air below the outside temperature.
• The A/C compressor will operate if the outside temperature is above approximately 6°C (43°F).
• The blower motor is on.
