most cooling fans are powered on by a relay in the systom.
the sencor completes the ground path that switches the relay and then the fan comes on

most cars the wires or relays go out and you have to replace them but i just hook a toggle switch up to it and run it inside the car to operate it that way cost about 6 dollars if that

I would run a jumper wire from the positive terminal on the battery to the fan and see if it comes on. if it doesn't your fan is bad. if it comes on start tracing backwards looking for broken wires or bad connections.
