Re: The most RIDICULOUS horn issue ever
Try this while the horn is blowing and the Cigar/horn fuse is installed:
Unplug the Horn relay. Then plug it back in.
If you can feel the relay click, the problem is not with the relay.
If you feel no click, replace the horn relay. In the meantime, try smacking the relay on the floor hard several times. Then plug it back in. Sometimes that "unsticks" them.
