The Refrigerant Cycle: Defrost

When DEFROST is selected:

• the mode doors direct airflow to the defroster duct and side window demisters. A small amount of airflow from the floor ducts is present.
• the recirculated air request button can be enabled, but can automatically turn off.
• the A/C is automatically commanded on and remains on until the system is either turned off or the airflow mode has changed and the A/C button is pressed.
• the A/C compressor operates as long as the outside temperature is above approximately 2°C (35.6°F).
• the blower motor is on and the speed is adjustable.
