Please help I have a husband that is Hospice patient and need wiring schematic for this ac unit. My brother started working on it and now cannot wire it back together. Heat/air unit and he got the heater working for the cold weather but now he can't figure out what the wires are for air conditioning. Multi speed blower. He replaced some parts and did not write anything down as to the wiring. My husband is really miserable and I was wondering if anyone could help me. It is the unit in the house and not the outside box. The unit below where you put the filters in. thank you
