There is no power to pin 1 and 3 on my Fan Control Module (1JO 919 506 Q) They say if I do not have power there, the basic throttle settings must be redone. Is that true? I am hot wiring my air con and it works fine, but the compressor has only 3 volts when tested through the normal harness. I have tried everything except the pressure and ambient temperature sensor. Please help !
