I can't find the radiator fan relay on my 2001 jeep cherokee larado with a v6 4.0 motor. could you tell me where it is?

There are 2 relays. Rad fan Hi and Lo. They are located under the hood in the fuse relay center

Sounds like maybe the relay is not working. Posible causes might be a bad relay, no power to the ralay, a grounded wire from relay to the PCM (computer) ect...

you probably have a bad solid state fan relay. This is a very common problem with jeeps. You'll love where they put this one. It is located under the passenger side headlamp assembly, but wait it gets better. The entire front headlamp grill support needs to be removed in order to gain access to the relay. The good thing is there is a shortcut that involves cutting a small hole in the headlamp/grill support under the passenger side headlamp assembly. I have a photo that shows where to make the hole and can post it if your interested in trying to tackle this yourself.

I have fixed my own 2002 Jeep Cherokee twice for the overheating issue. Overheating can be caused by a number of different problems, but one of the most notorious problems for the Jeep is the 'radiator fan relay switch'. When the temperature thermostat goes over 210, it tells the relay switch to turn on the radiator fan to cool down the engine. If that relay switch isn't working, the fan never turns on and thus your engine overheats. Here's a simple test to check if this is your overheating problem:
1. Start up your Jeep, open the hood, and let it run to the point where the temperature gauge on your dashboard creeps past 210.
2. Once it goes past 210, go over to the engine and see if the radiator fan kicked on. (the radiator fan is right behind the grill, circular with big plastic blades) If yes, then the relay switch is working. If no, then you probably need to replace the relay switch or the radiator fan motor is bad. But more than likely, it's the notorious relay switch.
3. Turn off the Jeep asap to avoid damaging the engine.

You can purchase a 'radiator fan relay switch' from most Jeep dealerships if they have a service dept. It should be around $75.
(I saved over $700 by not taking my Jeep to an auto shop to fix this) To change out the relay switch, you need to take off the passenger side front headlight. There's a black plastic guard behind the headlight and the relay switch is located under/behind that guard. If your Jeep ever experienced this problem before, you may see a cut-out where someone replaced this part before. If there's no cut-out, you can check out this link to see a picture of where to cut.

Once you switch out the part, you should be golden.

behind head light,, on passenger side, on fenders underside ,remove head light completely,, drill 2 inch hole into protective shield, this will expose switch

Likely your fan relay internal contacts have burned closed. Relay should be either in the power distribution center or in front of the battery.

Try to flush the system And inspect radiator. When moving the engine is also cooled by air. Make sure the water is circulating trough the manifold and the heater core. You can do this by atching a garden hose to each hose one at a time. You may also want to check the waterpump & thernostat..

Check your relay. I believe one of the terminal connections is an always hot connection. If your relay has gotten stuck in the on position, it will cause your fans to remain on.

Cooling fab relay is located in the PDC .. power distribution center by the battery its a black box with fuses and relays in it

the only problem that vehicle has is with cooling fans is relay/module or electrical harness to module that burns up located behind and under right front headlamp assy must remove headlamp to access relay/module that is what powers up fan motor module assy.
