Main function
The motor is connected with linkage which controls the air recirculation flap. The flap regulates air flow to the fan so that the air is retrieved from outside the cabin or from inside the cabin; there is no intermediate setting.







Type
The air recirculation flap has a DC motor. The ACC unit reverses output polarity in order to change the direction of motor rotation.







Connection
