Blower Motor With Blower Controller

The blower motor for generating the necessary air volume is fitted in the heater air conditioner. The blower features a symmetrical design and is equipped with two dual suction action radial fan wheels (four flute blower).

The blower controller is mounted directly on the housing of the blower motor. The controller features self diagnosis capabilities and is actuated by the control unit in the IHKA panel via the LIN bus. It is possible to replace the fan motor without the need to disassemble the instrument panel.
