Testing the fan is super simple. You run a jumper/lead from the positive side of the battery (or any 12v source) to the poower terminal on the fan & then ground the other lead that goes to the radiator switch to any part on the frame.

If the fan spins when you manually supply power, but doesn't on it's own then I would start checking the wiring between the fuse box & the fan for a pinch/break
