When my girlfriends Grand Cherokee overheated we assumed the thermostat was stuck so I went out and got a new thermostat and put it in. No dice! Next thing to do was check the fan unit by using a couple wires jumpered between the battery and the fan connector. Fan worked! Enter this part…. Ordered and delivered two days later. I took out the headlight as shown on the youtube vids and found the original had already ben replaced at least once. Dorman recommends you replace the harness with their new one and the old one looked like one of the pins was darker so I set about clipping and stripping all the wires. NOTE: this is where cell phones are awesome. i took a picture of the harness before I clipped the wires and so matching correct wire to correct wire was a snap. Install took maybe one hour with me making sure all connections were tight. I think the only way this part could be any better is if they included some shrink wrap in as well so one could make everything water tight. That would require a heat source though, so probably safer without. Fan worked perfect after install!
ONE THING TO NOTE; on the early 2000s Grand Cherokees they used vacuum lines to control the vents in the cabin as well as the cruise control. Many people have found that once one of those lines crack the system defaults to the defroster and no cruise control function. (or they pay a mechanic loads of cash to track it down) Anyway, if you take the headlight out you can see a vacuum canister behind where the headlight would be with a rubber hose connecting it and a plastic T connector. I just happened to look as I was replacing the relay and saw a broken dry rotted hose. 50 cents later and not only does my girlfriend have a functioning fan, but now her heater system and cruise control functions perfect again!

My 2003 WJ was overheating because the cooling fan wouldnt turn on and I decided to replace this relay. It didn’t fix my issue, so I moved on and replaced the entire cooling fan and shroud. That didn’t work either. I saw reviews that said these relays can go bad after an hour / day / week, etc. so I bought a Duralast relay from AutoZone. Fan worked right away. So I think the dorman relay burned out immediately. If you buy this and it doesn’t fix your cooling issue it may be worth buying a different brand. Pigtail worked just fine. Make sure you get the cords oriented correctly.

Excellent price, do the job.
I changed the fan as it’s certainly the reason why the previous controller failed. Old fan requires more power and this electronic controller don’t likes it.

Nice little solid state fan relay kit. Helpful parts included make a very good, but not totally perfect repair. Detailed instructions would help, e.g., why 2 screws and 2 rivets in kit?
What knocks out the old relay, I think, is rust. The 2 mounting screw holes in the frame, or the screws themselves, get rusty. A screw pops out, allowing the metal back of the relay to lift away from the frame, which is supposed to act as a giant heat sink to cool the relay. Without close frame contact for cooling, the relay overheats and fails.
Check the fit of the relay and supplied connector before installation. I had to bend the 4 pins up a little to get them to fit.
I chose to solder and use heat shrink tubing on my 4 wires instead of using the 4 crimp connectors. If you do use them, use a good crimping tool, then seal the ends with RTV to keep salt spray out of the connections.

In a 2001 Jeep Grand Cherokee, keep your eye on the temperature gauge. While sitting in heavy traffic on a hot day the needle begins going past the center mark, you just may have a fan issue. I did, and as long as the car was moving, no matter how hot the daytime temp was, the engine remained cool. But if I was stopped, with the engine running, up went the needle.
The cause was the electric fan not running. There are three choices: 1) Bad fuse, 2)Bad relay, or 3)Bad fan. I left out more esoteric causes as most unlikely. I started with the fuse: a 40 amp that was ok. The “relay” was actually this solid-state switch hidden under the passenger side headlight. There are instructions all over the internet for cutting a small rectangle of plastic under the headlight to see the placement of this switch module. It is firmly attached with silicon heat sink compound and screws, easily replaced in 10 minutes time.
I found that mine had already been replaced in some past year, prior to my owning the Jeep. It might have fixed the problem then, but it didn’t fix it now. Not the problem! Now I have a spare part. Woo-hoo!
That left the electric fan itself, which I found and replaced, somewhat easily. That is another story, for another review. Case closed, and the engine is cool again.
The Dorman switch was exact replacement. Plugged in like it was meant for the Jeep. I didn’t even need the extra stuff, like tie-wraps, that were included in the kit.

When you go looking for a cooling fan relay for the 2004 Grand Cherokee WJ everything will point you to this part. At least for mine this was not the case and there are two relays (high and low) located in the fuse box on the passenger side of the engine compartment. Mine were Tyco relays numbered 04848879AA 72472M. After MUCH searching I finally found a blurb online that the Mopar 4727370AA superseded the originals. I purchased those (on Amazon) and they were a great replacement, slightly smaller overall than the originals but the connectors lined up perfectly with the factory wiring connectors. They seem to work great and the cooling fan has been running fine with no overheating issues for several weeks now.
Still giving 5 stars, as the product looked great and I don’t believe it’s the manufacturers fault. Everyplace I looked indicated this was the part for the 2004 WJ. And I am just happy to find replacements for a part that theoretically doesn’t exist!
