About four things to do, first check voltage at horn with key on and button pressed. If voltage there try moving the small gap screw back and fourth a few times. If that doen't work replace horn. If no voltage check fuse and horn relay, you should be able to hear the relay click when you push the horn button, If not and fuse is ok. Switch relay out with another on on the car. If that doesn't fix it check the horn button for continuity.

Sun visor lights,... remove the sun visor clips you will find a copper insert inside the clip if this has broken (they do) you will need to replace them they 're about $12-15 ea. put them in & open your mirror "Gorgeous"
For the horn check the wire leads on the horn they are probably loose

Horn and heater may be fuse related. The headrests have nothing to do with fuses. The switch is bad or going that way for the seat or the motors for the headrests are out.
The horn fuse spin it, or replace as corrosion from aluminum fuses cause problems. I suggest replacing them all with new copper barrel fuses. The blower motor fan is a strip fuse on the driver side strut mount in a tootsie roll sized case.

The first thing a Tech (or I) would do in this case is check the BCM (body control module) for a fault code related to these issues. A scan tool will be needed to start this procedure. Otherwise, to guess at a cause would not be a cost effective or correct approach for diagnosis. Your vehicle has many circuits and control modules that control these accessories, and scanning the system will help pin point a solution.
