Have a friend, (or in-law) someone you're not too fond of, stand in front of the truck while you honk the horn and have them pinpoint it for you.

The relay is located under the glove compartment. Little difficult to get to but if you peek your head just underneath, you'll see it. Easy to take out and replace. Ive replaced mine and still have a problem. I hear a clicking noise and even can feel the contact when horn is pressed. I changed the horn about 1yr ago and now am wondering if the horn could have gone out so soon.
