I have a 2002 Chevy 2500HD Duramax/Allison. My horn doesn't work. I hear the 'relay" clicking in the fuse box, I have even switch relays around to see if it made a difference. I need it to pass state inspection. Does anyone have a wiring diagram for a horn or know where I can get one? Thnaks!!

Find the horn itself.....it's a diafram that needs to be cleaned....if it can't "buzz" no horn.

by you saying that you can here the relay clicking, tells me that the start of the circuit is fine (the end being the horn itself)

Thanks KarTuneMan!! That does make sense now. I will try and find the horn itself, however with this diesel engine taking up every inch of space, any clues where to start looking? Thanks so much !!!!!!!

usually behind the grill, or up along the fenders near the and under the hood
