    Default Its the speed controller for the a/c Heater blower

    motor.
    Also called the Limit switch , or on the e34 the slang term is Sword.

    On my SAAB 9k's it's called the fan speed control. It sticks out into the blower motor housing a four fin cast aluminum heat sink.

    Hey,
    Thanks!
    Seems like it won't be too bad to replace. The instructions look easy enough.
