The fan may be broken or the spots for power may have gone bad, to test the spots get a voltage tester and see if there is power. If there is power then try hooking 5 volts up to the fan and see if it spins. If it dont its junk. It may also just be stuck or dirty so clean it and try spinning it.
hmm.... just hook it up to 5 volts and it should work
Just test it with a Multimeter until you find a + and -
