Okay one of my fans isn't running while driving, but once it hits 3/4 on the thermo one of them begins to run. Anyone know what this could be and where i could get the part to fix it. I think it may be a relay but what do I know.
Thanks as always

what

Your question is model and year dependent.

I think the question was what happens when you turn your AC on, assuming it is working correctly. With the AC on, the fans should go to high speed.

shouldn't one fan be on at all times.?

no when it hits a certain temp the fans kick on low speed and another temp they kick in high speed

clarks-garage.com, garage shop manual, troubleshooting, cooling section has a great writeup on trouble shooting cooling problems.

okay just ran the car and they dont kick on at all till it hits the 3rd white line, and passenger kicks on thats it, then car begins to cool down.?????

ohh and the fans not broken because it moves just as freely as the other with my hand...

did you check the fuse in the fusebox each fan has its own fuse

replace the sensor in the radiator.

If you have the ability to remove the elec. fan assy, take it out and hotwire the fan that will not come on. Or if the connector is accesible you can do it in the car. Just as easy as running a power wire from a battery sorce, and grounding the other terminal. If it wont come on, the motor is fried. It would still turn by hand, but motor won't enguage if fried. Good Luck!

Check the wiring, the fan motor and the fuse.

If all is well, swap for a used fan relay.

if still no go, then check the resistors.
