Truck has a clutch fan from the factory. If you have an Efan it is one that someone else added, you will have to trace wires and find it yourself or post up pics of the setup.

I think the two wires go to the firewall on the passenger side above the starter solenoid.

Sounds like it may be a JDM Efan setup if it looks factory and runs to there. You'll need to post pics though, the JDM setup doesn't use fuses, only fusable links, even if you pop one cycling the key should reset it. Pics and a better description on the problem and we will get you squared away.

Definetly a JDM fan setup, lucky find if I do so say myself, its over $800 new. There is no fuses with that setup per say, so I would start with the temp sensor that screws into the side of the block, common issue. Does the fan work still when you turn the AC on?

We have very similar issues with our trucks lol...These two relays do fail and so does the sensor on the drivers side of the block. The replacement sensor is $35 and quality relays are about the same iirc(or more). I just ordered a much better adjustable e fan controller and harness from Mad...it comes with a much better setup and is only like $108. Killer customer service and if you need any help there are a lot of these in members trucks. I've been collecting how-to info and plan on installing and documenting the complete swap if you need help. I was buying the 30amp relays and frying them, sensors break...gets expensive. Hope this helps ya!

Could also be the AC relay in the fuse box under the hood is bad....it will most likely be the one with an odd wire coming out from under it lol...that relay also controls if the fan comes on when the AC cuts on.

I changed relays and let the truck warm up to192 and the fan still wont come on. I checked all the other fuses and relays to. Maybe the Temp sensor?

I jumped the fan and it wouldnt come on so i guess i have to start looking for another fan. I dont know if it would be cheaper to get a stock replacement or find one on line.

The e fans from Mustangs, Crown Vics, and Mark 8s are easily modded to fit our radiators and/or shrouds.

Try cleaning the prongs and leads with sand paper and then apply di electric grease unless its real bad. Mad enterprises should be able to hook you up with a harness (or a part#) if you can't find one.
