2000 SLS - no climate control fan

2000 SLS C/C blower motor not working. Have replaced the blower assy, the control module, and the temp control on the dash. Still nothing but much lighter pocketbook. Blower works great if I hotwire it. But I want to do it right. Need to find a wiring diagram for the temp control hookup and control module, as a wiring issue is all I can figure is left. Unless this thing routes through the body control module? I do know the motor wiring is center wire (purple) hot all the time, black is ground, and I have no idea what the unshielded wire does. The rear C/C works fine, so I assume the refrigerant side works. I know I can roll down the windows i this time of year, but winter is coming!
