What year is your jeep? Renix jeeps have a temp sensor in the radiator, its on the drivers side, about 6-8 inches down from the top of the radiator, it has 2 wires. The sensor for HO jeeps is on the thermostat housing. I think the fan is supposed to come on at 215-220, but Im not sure.. It could be the relay, your temp sensor may be bad, fan diode (rare), or a short somewhere..
