There is a relay in a panel on your fender under the hood. They are labelled: the fan is controlled by a relay. This relay is probably shorted. The relays that look the same are all identical: switch it out with another one and see if the fan stays off. If it does, replace the relay

The fan relay is stuck,Or there is a hot wire from the fan going to a constant on power source.Get a testlight from an auto parts store.They are indespensable for finding things wrong with your car.Just hook one end to groung and look for power.Battery negative is the easiest place,But any bare metal part will do.Then just check it to see if you have a good groung by putting the probe on the positive battery post and make sure it lights up so you don't go looking for powered wires with a bad ground connection on your testlight.
The fan relay is the first place I'd look. It's probably arced on the inside and made a permanent contact. Follow the wires from the fan to what ever it leads to and look for any damage to the wiring or if it had arched and attached itself to something with constant power.
Look in your fuse panel relay center under the hood and take out the one that says fan or cooling fan relay.Swap it with Another one from inside the panel and see if it starts to work with a different relay.Use a relay from something that won't cause it not to run like an Ac relay.
If it does which I think it will you've found the problem. Put the relay back from where you took it and get a new one for your fan.
There is also a switch that goes to the fan. Looks like an oil sending unit only on the radiator or engine block that could be stuck, and closing the circuit to make the fan constantly run. Un plug it and see if the fan stops.
Every thing your reading is for you to trouble shoot this yourself. You can find the problem on your own with this info.
And the last thing it could possibly be is the computer itself could be bad and sending a signal to tell the fan to stay on. Get one from a junk yard and save a ton. To trouble shoot the computer just plug in the one from the junk yard. If the fan works with the new one you just fixed it.

the ans were above is very correct but in addition to that you may have a bad sending unit that is keeping it on also, it is either one or the other for sure.
