2011 Jeep Compass with the 2.4

So far replaced thermostats and temp sensor. both fans do not run , even with Ac on and temp setting an alert.

fuses check good, fan relays and the box are clean and filled with dielectric grease and no corrosion found. Direct power to each fan via the relay terminals makes them run. AC fan only runs on high Rad fan runs on both speeds relays read as having power at their inputs.

My wiring does not match the wiring diagrams from alldata. where can I find a different wiring diagram that shows the correct wiring colors? Ac Fan wires are Green with red and Black with white that go to 2 different relays, Rad fan( right when facing vehicle ) has 2 purple or violet wires that go to 2 different relays

now down to assuming the trigger signals from tipm are questionable or a sensor is not sending the right info. still probing and checking to see if any relay signals change, but am now lost in the wiring

system stays cool while moving, but overheats quickly when stopped at idle

Dad in Garage going nuts APPRECIATE ANY INPUT

You said that the ralays are good but the fans will not run automaticly, If this gets too desperate then buy a temp switch and wire this to your fans .The fans do draw lots of current .My aftermarket fan takes 18Amps running at 12VDC .If the temp switch that you buy doesnot have a proper current rating then run the temp switch into your relay coils .Sure every vechile is a little different but erring on the side of caution I went for 70 degrees celcius
