Yes there is a fuse and should be marked look for it. you can also test for power at the horn this will mean the fuse is good.to do this some one will have to push the horn button for you. but remember power goes from the fuse to the horn button than to the horn, so if you have no power at the horn it could mean the horn button or clock spring depending on which your vehicle is equipped with are bad and if you have power at the horn it could be a bad ground or a bad horn good luck. please rate this answer.
