Hello, my name is***** cooling fans turn on if you start vehicle and unplug the coolant temp sensor? Thanks.
Ok, unplug the PCM and ground the dark green wire at pin 6 and that should turn fans on at low speed. Ground pin 5 and pin 6 at the same time and fans should turn on at high speed. Let me know how it goes, thanks.
