Thanks,
my AC. Is okay but no fan still on either.
any ideas on the compresser clutch activation
You can fit a toggle switch to turn ON the Aircon Clutch relay but maybe the system is low on refrigerant so the Low Refrigerant Sensor is stopping the clutch from engaging....forcing the clutch to engage with low refrigerant will destroy the compressor!
If you mean that the aircon clutch is engaging and you want to jumper +12 volts from the AC clutch to the cooling fan then you could run a wire from the AC relay pin 87 to the large cooling fan relay with a large diode in series with the wire. You may have to upgrade some fuses in this circuitry as the fan draws a fair amount of current
What year is your KJ so I can check the correct wiring diagram?
