what size fuse does the 79 bronco use for its A/C ?
I believe 20-30 amps is common for an A/C compressor, however, you may want to consult with an owner's manual or Haynes manual just to double-check.
I got a 198o ford bronco as a fixer up/ mudder and the air conditior fuse was 30 amp. hope this helps
