thanks for replying; I`ve attached a picture of the wiring so you can have a better idea of what`s what..hope it works....never done this before......I went to the furnace and my wife was turning breaker on and off and there was no clicking sound or nothing when the fan was turning on and off.....don`t see any contacts;just relays..i think the big red wire on the bottom right is the low power for the fan...i could pull that but then the motor would go straight to high ...probably not good....any help? thanks
