Ok here is the answer to your problem. Your cooling fan is controlled by a sensor relay which is located behind the left front head light and beneath the rubber molding. It held in place by two small screws. this module may cost you about $40.00 buck and you can with a few tools replace it your self. Once done your fan should work like new.

I had the same exact problem about 2 years ago. turned out to be the fan relay switch. i'm having the same exact problem now. just like last time i tested the fan by directly connecting it to the battery terminals to make sure the fan ran and it did, checked the fuses and they are fine again. i'm assuming that its the relay switch.....again. pain in the @ss! i dont remember exactly how i did it last time but i think i ended up having to remove the front bumber and possibly the splash gaurd in the wheel well of the front passenger side to get to it. its located in the worst, most insane location. for a $20 part that just unplugs to be replaced its riduculous the amount of work one has to go thru to change it. by the way, i got 100,000+ miles on my jeep now and i DONT regret ever buying it. its been good to me and apart from this relay switch issue 2 years ago its never let me down or left me stranded.

    found a link to pictures showing how someone replace their realay. they didnt do what i had to do last time which was removing the front bumper and etc..... all they did was to cut an access hole under the front light to access and replace the relay. genius! why didnt i think of that. anyway here is the url to the page with the picutures hope this helps everyone.

Although the relay can be the case in many instances, it can also be the fan itself. I, unfortunately, got to experience this last summer in Naples, FL in the summer where it is a bit hot. I was under the extended warranty and the dealer confirmed what I had thought: the fan itself was dead. I had tested all connections, relays, solenoids, etc (because it was cheaper than the deductible). Hopefully this is not the case but if it is and you are not under warranty you may want to shop around for a used or aftermarket fan (if they exist) as the dealer would have gotten a pretty penny for my repair.

2.4L so did you first idle it to get over heat,220f so it can kickon,
scanning the ECT s,proving it hit too hot,, per SM>??
the key here is what, a real schematic,
and a simple voltmeter
some jeeps also have a modulated fan.(and driver for it)
fuse 4, PDC good. tested?
it goes to fan relay , contacts and then to fan motor circuit breaker
no air pocket on top of engine,making, ECT lie?

if not the wire there bad,cut or pcm bad.
the PCM pin C2-p17 LG wire goes to relay pin 4
he PCM grounds this pin (using a transistor)
the relay closes, fan turns on.

Fan will not run when hot


Check fan relay. Remove passenger headlight, cut plastic to find relay. Replaced mine last night. Radiator fan spinning again. Was having temp spikes at start up and idling. Also bought coolant temp sensor but have not installed. Before I replaced fan relay, check engine light wasn't on. Now that the new relay is installed, light came on. Autozone and Discount Auto have an OBDII sensor you can borrow for free to read the codes stored on computer. Codes are generally stored when the check engine light comes on. Getting minr checked today. Will update solution later if needed. Relay was $55.

2002 jeep gr. cherokee laredo overheats only when sitting at an idle, temp comes back down when heater and fan are turned on full blast as long as jeep is moving


you electric fan probably isnt working with vehicle warmed up lift hood and watch temperature gauge when it starts to over heat check to see that fan is working if not it could be the fan relay or fan itself if the fan does turn on its most likley the thermostat

Car gets hot while idling, fuse is good, and fan does not come on with the AC... fan spins when manually pushed...


Fan does not necessarily get jammed when it fails.. Unplug the fan and hot wire it to the battery. If it comes on, it's good if not, change it. If it comes on when jumped, check the fan relay. Many jeeps have three fans. One that comes on with a/c, one that is operated by the temp control system and a mechanical one that comes on when the engine gets hot (has a heat sensitive lock up feature)
The automatic one operates as follows: temp sending unit sends signal to the computer which sends ground signal to the relay which then sends power to the fan. Likely that is the malfunctioning system you need to check. Some relays are in the power distribution center and sometimes the relay is tucked in front of the battery.

Over heating when sitting at idle for a short while


It sounds like it may be your electric cooling fan. When the car is sitting idling does the fan behind the radiator ever come on? If not then this is your problem. Your car doesn't overheat when it moving because you're passing air through the radiator with the movement of the car. The problem could be the fan itself, the fan relay, or a temperature sensor.

OVER HEATING


I just fixed this yesterday. Its your fan relay switch located behind your passenger side front headlight. I took my 2003 Jeep Cherokee to a mechanic and he could figure out the problem. I took it to a nicer mechanic and they were gunna charge me 600 bucks. I did a little research and ordered the relay switch online for only 40 bucks and changed it myself in like 10 minutes...

Saved me a bundle!

Do some research on line, there was one sight that really helped me but i don;t remeber it.

Search Fan Relay switch. .

good luck

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.
