Re: 69 with a/c engine compartment wiring
All 69's had the non A/C blower motor wire in the plastic wireway on the firewall above the engine. The A/C cars ahd a completely separate harness added to the car to connect the evaporator hardware and blower motor to the dash controls. The factory was suppossed to cut the non A/C blower motor wire off, tape up the lead and stuff it back into the wireway. Sometimes they forgot, or just stuffed the whole connector into the wireway. Its not connected to anything inside the car, since it originally would have come from the blower motor resistor bank that was in the inside heater core air duct box, which is obvioulsy not there in an a/c car.
If you have no speeds on the fan, check the fuse under the dash, then check to see if your compressor is engaging when you put the switch in A/C mode. If its not, check for power on the low temperature switch terminals (power to the clutch goes thru that connector) on the passenger side of the suitcase. If you don't have power there, but the fuse is good, then you have a problem with the low blow switch on the back left side of the heater control panel.
