Hi,
i have problem with 2012 wrangler jk 3.6, it is equipped with pwm controlled radiator fan,
ac makes fan spin and fan can be turned on via diagnostic tool,
but PCM does not command radiator fan, pwm control parameter stays at same level even when coolant starts to boil.
coolant temperature sensor was replaced, and pcm recognizes temperature,
is there another sensor that takes part in radiator fan control?
there are no dtc`s stored
Thanks in advance!
