2.4L so did you first idle it to get over heat,220f so it can kickon,
scanning the ECT s,proving it hit too hot,, per SM>??
the key here is what, a real schematic,
and a simple voltmeter
some jeeps also have a modulated fan.(and driver for it)
fuse 4, PDC good. tested?
it goes to fan relay , contacts and then to fan motor circuit breaker
no air pocket on top of engine,making, ECT lie?
i the pcm sees ECT overheat
it puts 12vdc across the fan relay coils
if not the wire there bad,cut or pcm bad.
the PCM pin C2-p17 LG wire goes to relay pin 4
he PCM grounds this pin (using a transistor)
the relay closes, fan turns on.
