clicking sound by the fuse box and horn doesn’t work

Sebastian Bermudez  If it only clicks when you press the horn button it is probably your horn relay that clicks and in your case it may be the horn that has failed. Apply direct voltage to the contact of the horn and see if it works. Negative to horn housing and positive to the horn contact where the cable connects to.

If this clicking is a clicking that is there all the time you will have to get closer to it and identify the part that is clicking. you can then go ahead and post some pictures of that so we can try to identify it.
