Air Mix Door Motors
The driver and front passenger air mix door motors are attached to the front heater & cooling unit. The rear air mix door motor is attached to the rear
heater & cooling unit. These motors rotate so that the air mix door is opened or closed to a position set by the front (or rear) air control. Motor rotation is
then conveyed through a shaft and the air mix door position is then fed back to the front air control by the PBR built into the air mix door motors.
