1965 Dart A/C system help!

I'm not sure! If I see the wiring in the car the power cable goes to the A/C switch. The A/C switch supplies the blower motor resistor with power and from there to the blower motor switch and on to the heater motor. I don't get any power at the heater motor or the blower motor switch.

Are the cables right connected? I have a lot of stuff for 1965 Dart but no wiring system on this A/C unit!!!
