I have what started out as a fan blower replacement need.On the roof The blower squeeked horribly so i replaced it.But now when it calls for heat, The fan only goes on, on (on) Auto doesnt kick the fan on. And the wires must be wrong because now i have the Condenser fan and the compressors' running.Can you help me on this one?

sounds like miswiring or no voltage on auto side rather than low voltage my guess
