Heater Wiring
Alright, just got a 76 f100 on the road. It has factory A/C too. The heater controls (guess the fan really) wont turn on. I didnt see any fuses out either. I'm just wondering if anyone can point me in the right direction in the wires, as to where the heater gets its power, just like a wire I can put the multimeter on or something. THANKS!

A/C controls are usually vacuum actuated.
You can look under the dash on the heater box for the resistor.
There should be a 30 amp fuse to check.
I'll see if I can find an illustration.
