Is it a pull towards you to flash the high beams and a push away to lock them on then pull back to turn them off?

Has there been any wiring changes lately?

the 94 should be pull to flash people an push to "lock" it. might be a bad wire or a bad switch.. their really not bad to pull apart. i had to pull mine apart to fix my blinkers.

How do you know the fan was wired wrong? Was it working before you changed anything? Were the high beams and indicators working before you changed them?

Sounds like you should be blaming yourself for messing up the wiring rather than someone else. LOL

You need to calm down there a little bit and relax there son. Maybe get some spelling and grammar lessons as well. j/k

Why would you wire it to a switch. It should go from the sensor on the block to a relay. The relay will have a direct feed from the battery or distribution block through a short stop (resetting breaker basically). Upon the sensor tripping at the proper temp it triggers the relay (in a sense like your hard wired switch) which then provides power for the fan. Most e-fans on startup can take around 40+ Amps then drop to about 20'ish to just run.

If the fan stopped running all of a sudden look for a short (causing the breaker to trip), or the in block sensor has failed. The in block sensor (if memory serves) is at the front of the block and has a single wire coming off of it. Or is that the gauge sensor in that spot? Crap, I can't remember which and I don't have my book handy. It should be easy enough to back trace the wires to the sensor. Testing one of those sensors is easy, it is just a dielectric switch, test it with a VOM and hot water. It will drop to 0 Ohms across the body to the pin when dropped in hot water (boiling works).

roadkill sorry about that i was just having a bad an that didnt help when u said that an i took it the wrong way sorry

but ya why i wired it to a switch was that me an my pops changed everything new block sensor, new relay, and put new wire from the fan to the relay and new blcok sensor and it still didnt work the temp would fly up to about 220 in about 5-10 min so i had to beable to drive my truck to get to school and work so we wired it to a fan and my truck never gets past 160 now, when i have a break from work im goin to take it to my mechanic and get him to check over everything so for now i just have it wired to a switch so i can drive my truck without over heating it.

and sorry again for flipping out my bad

Was there a fuse or short stop (looks like a metal block with two bolts sticking out of it) in there as well some where? I wonder if the short stop died or the fuse is toast?

So with a new block sensor, relay, and wires the fuse/breaker(short stop) is about all in that whole circuit. You know the fan works on a switch (hopefully fused). I'd start by checking for a fuse/breaker, then take a VOM and check your voltages at all the different spots they connect. It's a really simple circuit and is isolated from everything else so it will be easy to troubleshoot the fan. Just take it one step at a time and be thorough.

As for the high beam indicator, it sounds like there is a wire crossed in either the switch or one of the many possible connections on its way to the dash. I'll look in my explorer manual to check it's wiring diagram as well as my Ford service CD. I think I have one for a '94 era truck. If it's not too large of a file I may be able to send you a copy of it for reference if you don't have a Haynes/Chiltons manual.

BTW: Don't sweat it. We all have bad days. They don't seem to get any better sometimes as you get older either.

ok cool thanks ya i got one of those reapair manuals for the 94 and up ranger?? if thats what u mean. also yes the fan is wired to a fuse before the switch and ill have to check all the fuses to see but i notice today when i was driving to school it went off?? for the first time in 2 days and it hasnt came on again but now its the e brake light is on but very faint and just enough to tell that its glowing lol my truck has a mind of its own i swear it just likes to bug me with crap like this. so im goin to have to go over all the wires behind the dash

an ya could a loose ground wire cause some of this??

Must be gremlins! LOL

The e-brake light being on can mean low brake fluid. It usually just lights right up though. Bad grounds (engine or otherwise) can cause lots of little odd problems in the electrical. After all that power has to go somewhere else to get back to the battery (in essence).
