[RESOLVED] Radiator fan HELP....IM stumped

[ryno]

Ok so out of nowhere my passenger side radiator fan decided to stop working.(the main fan)
And I cannot find the reason. It just randomly stopped. And now my car is running off my AC side fan(that i have hooked up to a manual switch) but tis not getting the job done too good.
Things I have checked:
Relays are good
Fuse is good
Fan is still good ### i tested by hooking the wires straigh to my battery and it still came on
Im throwing no CEL, therefore i wouldnt think a sesnor(engine coolant temp) would be bad.

What are my other options, i cant stand this fan not working, it is 100' here in ID, and my car aint liking it too much.

Is there a possibility the sensor is bad and not throwing a code? And would this effect the fan not turning on?

thanks

I would check the fan wires to be sure they are not broken anyplace. If they are good and you know the fuses & relays are good I would go with a new coolant temp sensor.

would a fan still come on hardwired like i did and maybe not when plugged into the wiring harness? if that makes sense?

Yes, you could have a good fan and a bad wire. You jumped the fan off another wire to the fan right?

I used the wires that came straight off the fan, but i could have a bad wire from the main harness on the car. But it runs straight into the big wiring harness and who knows where to look after that

Yeah, just take out cooling fan relay and put a jumper on the terminals.

It was a faulty fan afterall. thanks

how did you test to find out if the fan was defective. I think I might be shorting out somewhere but I would like to test my fan a lottle better than just hooking a wire up to the battery.
