Front Defrost Setting

The blower motor turns ON. You may manually adjust the blower speed using the fan switch. The A/C compressor activates if the outside temperature is above 3°C (38°F).

The IPM energizes the air inlet and mode actuators to:
^ Open the defroster door
^ Position the air inlet door to the outside air position
^ Position the A/C door to direct a small amount of air through the floor outlets

The IPM energizes the air mix actuators to:
^ Determine the proper air discharge temperatures
^ Position the air mix valves accordingly

The A/C compressor may still operate in Defrost even if A/C OFF is selected. The A/C OFF request will be applied to the next manual mode selected.

You cannot force Recirc in Defrost.
