so i notice my car was overheating and i checked coolant and water pump, and all that stuff to make sure it is working. and i noticed the fans have stopped coming on! i tried changing the relays and that didnt work.
i made sure the connections were still good as they are, so i have no idea what the problem could be????
am i going to have to wire them manually?
Do you possibly think the motor in the fans went bad?
I would take a break first to have some pork flied lice before troubleshooting those frans...Quote:

well they were working and one day when i went to drive it i noticed the temp would get higher then go down as i drove, so when i got it home i opened the hood and noticed the fans were not working.
i dont think both fan motors would go bad at once.
im at a loss on this one.
What kind of thermostat you got? Or did you rule that out in your overlook?
Have the fans been reprogrammed to come on at a lower temp? If not, the factory setting for the first fan is 226. You would have to run the engine up to this temp and confirm it with a scan if able before you could truly say the fans were not working. If you haven't already, check out this site....

well considering by the time i got it home it was near the 260 mark confirms it was hot enough and i can see my fans when i pop the hood and they are not moving.
Tstat has bee replaced, and yes fans have been reprogramed. this weekend im going to try and jump one fan to see if it will come on.
i know 100% that my fans are not working and everything else is. its bizar
Check if you are getting power out of the relays. If yes, go to the fan connectors to see if you have power.
Did you check the fusible links to see if any of them fried? When I lost a motor, one of the fusible links fried. Replaced the link and the motor, all was well.
i didnt see a fusable link
where is it?
i had the same problem, installed slp fan controller, fans both work, relays are good. in my case i think i have bad output drivers in the ecu, still never solved the prob, reprogrammed fans tooo
the Temp senser will make your fans not work if its bad or going bad check it. A lot if the time if you turn your AC on it will turn your fans on try that also .
in my case that was the first thing i ever replaced. and yes (for a 94 at least) the a/c or defrost will kick on the fan, just low speed think. 93 has a different fan set up as far as wiring goes and some 94 have the earlier style as well. IM pretty sure its all on shoebox's website. temp sensors on water pump housingQuote:

the sensor is real cheap, i would replace it and see what happensQuote:

do the fans kick on if you turn your AC on? that should override the sensors and automatically kick them on.
i have no smog syuff and no ac or heating equipment on the car. i dont even have the controls in the dash
am i looking for a temp switch or a coolant temp sensor?
the temp smitch controls the guage, im not sure what the difference is
The sensor for the gauge is in the driverside head, the sensor for the computer is in the waterpump.
ok and im assuming i need the one for the comp.???
since the guage is working fine.
That is what they have been trying to tell you. The sensor is not the same part # as the one in the head.

Have you done any actual troubleshooting?

ok so all the wiring looks good, nothing is burned or broke. i replaced the sensor and that didnt work. fuse was replaced even though it looked ok, relays are working also.
so now i think im just going to pull the stock fans and run an after market one, or bypass the comp and run fans to a switch
