I did an engine replacement I have the entire working harness plugged in but my electric radiator fan wont kick on and my truck runs hot. It will not even kick on when I turn the air conditioner on high what could the problem be?

It could be the motor fuse (J13) or relay these guides will help us test the motor for power and ground and to check the fuse and relays, here is the cooling fan wiring diagrams so you can see how the system works. I have also included the fuse and relay location as well.

Check out the diagrams (Below). Let us know what happens and please upload pictures or videos of the problem.
