Defrost Mode

when the mode rotary knob is in the DEFROST position, the defroster control cable moves the defroster valve in order to fully uncover the opening to the defroster nozzle. This restricts the opening to the heater duct. This delivers the maximum airflow to the defroster, with only a small amount of the airflow exiting out of the heater duct.
