Hi

Does anyone know if there is a way to bypass the internal fan resistor in the facelift 156. I bought a new fan and plugged it in but it is still not working. The fan works when connected directly to a 12v supply. Testing the cabling in the car with a multimeter shows that there is 12 volts but no amperage when moving the speed dial. Therefore I assume it is the resistor.

Thanks

The resistor acts as a speed regulator, you need to replace for the fan to work correctly.

It should look something like this:


or this
