Hvac control issues
My car is originally a 85 non ac car, the dash harness has been changed to an 86 ac/heat harness with controls. Not my doing this was done to prep the car for a efi 5.0, the heater box stayed the same non ac. I want the heater to work so i can defrost the windshield, but i have no power at the switches except for the rear defrost switch that has power but it's not needed as this is a coupe. Where should i start to find a fix for my issue? I have 12v at the 30amp fuse but no wire at the heater box nor switches show power, I'm stumped...

Fwiw, it's a good idea to put at least the general area in your profile.
Working on cars in SoCal is often very different than working on cars in snow areas.
