Cooling fan only works when I pull the 50 amp fuse and put it back in. Then the fan does not shut off till I turn the jeep off. It ove heated the other day because fan did not turn on. The relays, (the two in the fuse box under the hood) tested ok. I replaced the coolant sensor and the fan motor. I found another relay of some kind or a sensor under the battery box mounted on a brace when I pulled the bad radiator. Is this a fan relay also. Any help appreciated.
