The horn does not work and I need to check the fuse and relay. I believe that they are located under the hood in the black rectangular box above the engine on the firewall but how do I open the electrical box?

THIS COULD BE A FUSE ISSUE. CHECK ALL THE FUSES FIRST. I BELIEVE THAT THE HORN FUSE IS LOCATED UNDER THE HOOD. I HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR USING FIX-YA.

This happened to me, crawl under front of car drivers side with a metal coat hanger, make a 90 degree bend on end of hanger & start fishing for the lever, just keep bending the hanger & take your time it can be done.The hole in the metal you will be fishing thru is only about 4" square. When you catch the lever gently pull towards drivers side of car. Tom-Ala

Check fusible links coming off of the starter, with the battery disconnected.
Pull on the various colored wires that have a barrel of foam on them about 1/2" to 2/3" long that indicated that the wire is a fusible link.
If a fusible link stretches, the inside of it is blown. Many circuits can be controlled by the fusible links.

REPLACEMENT
Fuses protect all the major electrical systems in the car. In case of an
electrical overload, the fuse melts, breaking the circuit and stopping the flow
of electricity.
If a fuse blows, the cause should be investigated and corrected before the
installation of a new fuse. This, however, is easier to say than to do. Because
each fuse protects a limited number of components, your job is narrowed down
somewhat.
Fig. 1: Fuses come in different colors which indicate different
amperage ratings
The amperage of each fuse and the circuit it protects are marked on the fuse
box, which is located under the left side (driver's side) of the instrument
panel and pulls down for easy access. To replace a fuse, simply pull it from the
panel. Insert a new (same amp rating) fuse in its place.

possible horn itself is faulty and needs replacing. you will need to locate where the horn is and apply power to the horn from the battery. if the horn sounds then you know that it is a broken wire th=o the horn
