SOURCE: cooling fan not working

The fans only run when the engine reaches approxminatly 235 degrees F. on the guage that is near the end of scale just before guage show "HOT" I don't think you have a problem, allot of folks out there don't know about this.

SOURCE: Cooling fan

there are relays not just fuses for the cooling fan. look under the hood there should be a black junction box open it and you will see several little black cubes those are relays. if you have the owners manual they will show what each one is for. start the vehicle and let it get to operating temp 180-190 degrees your fans normally kick on at this point what i normally do is take the relay for the a/c clutch and swap it for the radiator cooling fan if the fans kick on you know it was the relay. if they don't kick on then you know that the temp sensor on the radiator is bad., but before you go replacing anything make sure that there are no loose or missing wires. that all mplug connections are tight and not coroded and that with the engine off that the fan blades spin freely. once checking everything and you still have an issue then the fans are bad and need to replace it.. please rate this thanks

SOURCE: where is the fuse or relay for the cooling fan in

You have to refer to your owners manual or an after market service manual for fuse locations but that is not the issue. There is a sending unit screwed into the block with a temp sensor that closes the circuit on the ground side when the cooling system reaches a specified temperature. There is a fuse between the hot side and the fan for over current protection (see manual). A bad sending unit is most likely the culprit. Measure the resistance or continuity when the engine is hot from the sending unit body which is grounded to the block, and the output terminal or black wire running to the fan motor. It should be closed or read less than 0.5 Ohms. If it is open or very high resistance replace it. Good luck to you. I hope thishelps

I have a 89 firebird cooling fan don't come on I'm


have you check to make sure the cooling fan is working and not seized. this is a common problem with most cars. this is where I would start then go to the relay. the relay is usually mounted on the firewall under the hood and there is a plastic cover that covers a row of relays. don`t remember which one is for the cooling fan though, they may be marked on the underside of the cover.

Are you getting a ground signal from the engine computer to turn the fan relays on ?
The computer grounds the relay when the engine temp reaches 220 degrees, or when the ac compressor is running.

Which fuse goes to the cooling fan


there is fuse and a relay for the cooling fan.just turn ignition on and test all the fuses(some fuses will only work with the system on like headlights/tail lights).check the relay in the relay box(panel)under the hood.you may have a bad cooling fan,you don`t say why your checking the fuse.if you unplug the connector at the cooling fan and jumper a ground wire and power wire it should work.if not then you need a cooling fan motor or assembly.

Engine cooling fan not running checked fuse ok


I would check the fan first disconnect the electrical connectors on it and use a pair of home made jumper cables and run it from the battery. If it works move unto relay if it doesn't you've found the culprit.
Next check relay in the fuse box. Coolant tempertant switch and its circuit aka thermal switch in the water jacket by the t-stat.
