Titan 4WD V8-5.6L (VK56DE) (2006)
The driver and front passenger air mix door motors are attached to the front heater & cooling unit assembly. The rear air mix door motor is attached to
the rear heater & cooling unit assembly. 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.
