check ur wiring. i tink u can google for the wiring diagram. also, when u trace it to the engine, check for chaffing on the wires by the horn. it could also be a dead horn and u jus need to change it. i'd go for the air horn upgrade anytime! lmfao!
too bad mine aint dead yet.

I believe the horn is ahead/below the battery on the passenger side. I think you get to it by reaching up from below the bumper/laying under the truck. Seems like it's easy to see when your changing the external tranny filter. Been a little while since I was under that end of the truck & too cold to go do it right now. Yes, I'm that lazy some days.

Appears my Google-foo is weak today for some reason but I can't find the wiring diagram 
If anyone has it hook a brotha up , no hurry gonna be playin Santa for a few days but I'll tinker around with it after that....
Cruise works fine so I don't think it's the clock spring and the fuse is good so it's gotta be a bad horn or a wiring issue.... Is there a way just to ground the wires at the horn to eliminate / or prove that it's the culprit ?
Thanks fellas

zhilton has a good idea, exbowtieguy. i completely missed it. tat whole 12v hot wire. yep. if it dont work, either a bad horn or crappy ground wire. wont be tat hard to trace by tat point when ur under there. although i rarely hear a dead horn. they dont seem to die tat easily, do they? i'm leaning towards the train horn package. hehehe.

I know its a dual tone horn, and on my 05 at least one of them was in my passenger side fender. Saw it through on of the holes, said to h#// with that and just wired up my new one to a switch.

horn is is side passanger fender well.
remove fender liner. disconnect horn, put test ligh in place of horn. hit horn button and see if test ligh blub lights up. if so you need a horn. pretty simple.
