the speed resistor is for the blower motor, not the condenser fan motor right !! i'm having problems with the condenser fan not coming on with the a/c with a code 141
Hi, Sorry for the delay and thanks for the assitance bmwforeman.
It was not clear ifn your first question that it wad the electric fan in front of the radator, so now we are clear on which part is faulty.
The fan is a two speed fan which operates with the a/c and when the engine over heats it will not work until the engine temp gets well past the halfway on the gauge.
There is a sensor with a three pin plug in the side of the radator that if you bridge the wires two at time you can make the fan work on both speeds one at a time, it is possible to have one speed fail and the other still work. you should also hear the relay click. hope this is more helpfull.
