No map lights or horn

The horns are on their own circuit with a 20A mini fuse in the junction box under the hood. Did you test that fuse? Don't ever rely on a visual inspection of a fuse (especially an old one) - they can look fine but still be blown. Always use a tester or replace with a known good fuse.
Do your rear seat courtesy lamps and trunk light work? They are on the same circuit as the map lights so if they work then you can eliminate fuses or the BCM as the source of the problem. If so, you should check for power on the dark blue/white wire at the rear view mirror. If no power then you have a wiring break between the BCM and the mirror. If there is power then your mirror may have to be replaced.
