Blower With Blower Regulator
WARNING: This page does not describe the selected car, but rather 33 other vehicles, including the 2010 BMW M5, 2009 BMW M5, 2008 BMW M5, 2008 BMW 760Li, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
The blower generates the necessary airflow. The blower is installed after the evaporator in the heating/air-conditioning system (suction fan) and is equipped with 2 blower wheels.
The blower regulator is fitted directly on the blower motor housing. The blower regulator is capable of self-diagnosis. The blower regulator is actuated by the IHKA control unit (via the LIN bus). The blower regulator controls the blower motor with a pulse-modulated signal (PWM signal).
