Location 

The blower motor is located on the right below the glove compartment in the air conditioner housing.

Task 

The blower motor delivers fresh air or air from the interior compartment depending on the position of the fresh air/air recirculation flap through the air conditioner housing into the vehicle interior.

Function 

Depending on the blower stage setting, the AAC [KLA] control unit (N22/1) sends a control signal over the AC LIN to the blower regulator (A32n1). The blower regulator then regulates the operating voltage for the blower motor.
