System Airflow Description - Manual Climate Control: Defrost

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 door and floor/defrost door vacuum control motors are at no vacuum, directing airflow to the defroster duct and side window demisters. A small amount of airflow from the instrument panel A/C registers and floor duct will be present.
• Blended air temperature is available.
• The A/C request button will not illuminate and is disabled. To reduce fogging, the A/C compressor will operate automatically if the outside temperature is above approximately 2°C (35°F).
• The blower motor is ON.
• The auxiliary blower motor is enabled, if equipped.
