As a first guess, I'd say that the windings on the compressor clutch magnet might be shorted (at least partially). You could get the pulley/clutch assembly off a salvage yard car and try it. Parts out in the moving/vibrating/oil-covered/dirty end of things experience failures. Clutch coils,

You might also want to check the low-pressure cutout switch that (if I recall) is located down low in front of the right fender next to the radiator. If that has gone bad/funky nothing will come on. You could just short it and see if things come on. Probably doesn't relate to the horn
