Bought one from Bruce and it worked for a day. I had hoped that it would have lasted longer. Contacted customer service and they asked me to test it. It turns out that the resistor’s ohm testing isn’t much use so I had to dig deeper and find what each of the 4 wires to the resistor did and where they came from. I was getting the varying voltages from the fan speed switch which at first shocked me but lots of googling later I found that was normal. Another thing that I wasn’t used to was the switching of the earth not the power side which is also the new normal with these modern CANBUS systems. Jumping the switched earth from the resistor plug across to the fan and similarly with the positive wire proved the blower fan was fine. I sent through my results of testing and a replacement was sent. Just installed it and all is good for now. Can’t complain about the customer service. It isn’t their fault if the part they sell is a lemon. I have purchased motorbike parts from Bruceshark in the past and no lemons then.
