Does anyone have a wiring diagram that shows anything for the a/c & heater controls. My book seems to always have just enough info to get me nowhere. My blower motor is not working. I have power at the big red wire that goes to what I'm guessing is a relay that's bolted to the blower motor housing. I don't have power to any of the connectors on the control unit. Also there is one connector that splits, if I remember right off of the plug that goes to the blower speed selector switch that isn't hooked up. It is a black wire. I can't find a match for it.
