Jeep Tj Radiator Fan Not Working

2003 jeep wrangler tj 2 4l my coolant fan won t come on.

Jeep tj radiator fan not working.

If this resistor begins to fail then you will see air blow at only some of the fan speed settings. The main fan was working i never saw it go off even though i was just idling from a cold start in the driveway. Just because the radiator fan is not on does not mean that it is not working. However the fan in front of the radiator did not come on.

Crdmiller i flew up to a little town in montana and drove it back. I hot wire fan to the battery it comes on posted by michael iannone on feb 10 2017. Should the resistor entirely fail then no air will flow through the jeep s vents at all. Recently i was driving my 2015 jeep wrangler jk unlimited through a parking lot on a 95 degree day and after leaving a stop sign a check engine light flashed on later i would learn it was a p0480 cooling fan relay 1 control circuit and shortly thereafter my jeep overheated.

Attach another jumper wire to the other terminal connecting it to the negative battery terminal. I replaced the coolant senser the relay and fuse still won t come on. Blacklibertycrd i turned on the a c as you suggested. If the radiator fan is not working it s a serious problem.

Your jeep commander s radiator fan has one of the most important jobs on the vehicle. Connect the other end of the jumper wire to the positive battery terminal. Should the blower motor seem fine and pressure is not an issue but the fan only works on some speeds then it could indicate a problem with the resistor. It is the last line of defense between you and an overheating engine.
