Heater Mode

When the mode rotary knob is in the HEATER position, the defroster valve remains closed. As a result, the air from the blower fan receives heat. This air goes to the defroster valve. The defroster valve sends most of the airflow to the heater duct, with some of the air going to the defroster nozzle.
