I have a 2009 4.0 that i replaced the radiator, and the cooling fan on. I put the same fan on that i took off. I replaced the temp sensor on top of the motor, new thermostat too. I have checked all the fuses and relays, and they are good. When i unplug the temp sensor the fan will kick on. but when i plug it back in, it goes off. I have tried turning on the heater, defrost and nothing works. Now the AC dont work. I don't know how it was working before i changed out the fan and radiator because it had been wreaked. nothing with the motor just front finder and tire. Would Love to get some help please!!
