benefit resistance

I have MB W126 500 Sel vm.86 and now heatingblower begin to make nasty noise. I have changed new motor in heatingblower and it´s not helping.
Now repair man says that part Bosch 1 147 328 074 ---> benefit resistance has to be changed.
Could anybody know, where I can find this part in used?

You should be able to see that the part you are trying to replace is solid state and can make no noise. It's only funtion is to reduce the speed of the blower - again no affect on noise. New or otherwise, something is wrong with your blower motor.

Could be your fan is rubbing on the housing, or something along those lines.
