I need to know how to change the polarity of my electric fan motor so I can use it as a pusher instead of a puller. The fan I have says this can be done but does not give any instructions . The only thing it states is to remove the blade and turn it over and reverse polarity of the motor. The fan only has two wires 1 is blue (hot) and the other is black (ground).

Thanks in advance, Ray
