Climate Control System - System Operation and Component Description: Defrost

When DEFROST mode is selected:

• the recirculated air request button is disabled. The air inlet door opens, allowing only outside air into the passenger compartment.
• the air distribution doors operate simultaneously to direct airflow to the defroster duct and the side window demisters. A small amount of airflow from the floor duct is present.
• blended air temperature is available. Only when A/C compressor operation has been selected by pressing the A/C button (indicator on) can the airflow temperature be cooled below the outside air temperature.
• the blower motor is on and the speed is adjustable.
