Now pull the power wire off and connect a +12V feed directly from the batter positive terminal to the motor terminal. If the motor works, the problem is in the control wiring. If the motor doesn't turn, replace the motor.
    I'll go about testing the fan motor when I have more time. On the other hand, I have a suspicion that it might be a fuse.
