Will it run with the key off? If it will then the relay is stuck closed, if it shuts off with the key then the fan sensor is defective. Or someone hooked it up to power source that turns on with the key.

tennisshoes I tow this car and ALWAYS remove the fuse that unlocks the steering wheel, the key remains in ACC while towing. Would this have anything to do with "power source that turns on key"?

The ignition switch is what turns on all of the power for your car to run, if you have the switch in ACC position you are suppling power to all of the accessories ie radio, wipers, on some models the heater fan. I don't know why you have the key in the ACC position while towing. Have you tried disconnecting the battery, push the brake pedal at least 3 times then reconnect the battery and restart the car to see if that clears the problem?

Can you tell me where the FAN SENSOR is located?

It should be located next to the oil fill tube close to 2 pipes.
