    Fan will not come on in cool but will in heat
    Fan will not come on in cool but will in heat. Also fan will run when set to off and fan is in the auto position. A switch was replaced back in the winter. I am wondering where I can find a wiring diagram that will show me the switches wiring. There is two switches inside the cover on the inside unit. I think the switch may be wired wrong. I found a red wire in the floor under the unit but I do not know if it was left out or may have been replaced.

    Will the blower come on if you turn the fan switch to on at the thermostat? If it runs in the fan on position and not the auto position you have a bad thermostat or its wired wrong.
