I have an '87 B2600 and the horn stopped working. The relay makes a 'click' sound when I depress the horn button. I wondered if it was bad and decided to replace it. No difference. So, does anyone know where the actual horn is located? I can't find it and am starting to think it fell off! Please let me know if you have a clue. Thanks!

your horn is located in the same spot as a b2200, passenger side in the front easiest way to get at it is to pull your front bumber off and you will see it or buy a new horn and mount it in front of your battery and connect the wires
