    Tom I dont know much about cars but mine quit working last summer. I just took it out and ran it into Auto Zone. They tested it and the motor was bad. Easy fix and was like $20 if I remember right. This could be it brother, just trying to help.

    Tom, you should be able to unplug the fan (somewhere close to the fan) & jumper it directly to the battery & see if it'll run. If it does, you may have a bad thermostat (which controls the fan) of something preventing power to make it to the fan (fuse, wiring problem, etc.). If it doesn't, you probably have a bad motor.

    Also, don't let your motor overheat. Aluminum motors can't take the abuse the older cast ones did.

    There are several factors that can cause the electric fan not to work test the fan motor first if it works then your in for the fun can be a wire shorted can be the temp sensor causing it the list is long but check the simple basic stuff first like the fan motor to make sure it isnt it.

    Good Morning, There Will Be 2 Heavy Gauge Wirs Coming From The Fan Motor, 1 Should Be Red (Pos) & 1 Should Be Black (Neg). Take Any Insulated Wire & Jumper It To The Red Wire, After You Disconnect It @ The Connector, Located Closest To The Fan. It Should Start To Turn Then.

    How Long Ago Has It Been Since You Flushed Your Cooling System ?

    Either PM Me Or Post On The Thread With Your Results, I'll Help You Get This Fixed This AM, Elliot

    I would start by using a test light at the fan with the engine running warm and see if the fan is getting power. If it is thenm straight wire it to see if the fan is burned up. If there is no power to the fan I would start working my way back toward the fuse box testing the power at each junction/relay. The fords have a few relays and temp sensors to turn the fan on only when needed. A simple test light and a few patient minutes of testing can usually find the problem. Also, any repair manual for that vehicle will list the wiring diagram and include all relays and sensors.

    Good luck.

    Take The Yellow Wire With Your Lamp Cord Touch It To The Pos. Side Of Your Battery While Touching The Black Wire To The Neg. Side Of The Battery, The Fan Should Turn.

    Caution: Make sure the fan is clear of obstructions. Fingers ,shirt sleeves. wires ect., be cafeful when working around the fan and wiring. Also don't let the bare wire touch each other when connected to the battery.

    once you undo the clip to the fan there are no wires coming out anymore it clips(mounts)flush to the fan once clip is removed it exposes the three prongs for the clip to attach to inside the motor its self,i touched all three one at a time to the wire i am useing as a jumper and nothing happened does this thing have to be grounded?or should it work just my touching the positive cable to the right prong?,also fan motor seems very stiff to me, i am begining to think its bad,since i have touched all three prongs and nothing happened

    Tom, IMHO you need to get a friend with a lot of mech. knowledge to give you a hand. I have been doing all kinds of automotive repair work for years. One of the hardest things to fix is something that someone has gone into and destroyed something by testing or taking apart wrong. Your fan is controlled by a sensor on the engine--this sends info to computer--computer controls fan coming on or off as needed. System is protected by relay, fuses, and fuse links. If you have no idea what you are looking for you can do some very expensive damage by jumping something improperly. I could try to tell you how to wire it up so it would run all the time but that is not a fix, just a temp. way to something serious. I don't try to repair my computer or television just because I can get the cover off and I have a pair of plyers and a screwdriver. Be careful you can harm yourself and your vehicle !
