Horn not working.

Do you know if it’s the same on a 03 tahoe ?

Hey Perro, I had the same problem with mine when I got it. My brown wires were together already and I spent a lot of time checking wires, pulling the steering wheel, and other stuff. Then I decided to check voltage at the horn to see if they were bad. Got out the circuit test light and sure enough both horns were getting power when you pushed the horn (needed a partner for that). Switched out the horns and now they work! I don’t know what would cause both horns to go bad but they were and it was a pretty cheap fix!

Thank you guys, this thread was very helpful. Got my horn working.

Is that bundle of wires on the right side of the center console? I see that in the diagram just want to ensure it's right before I start ripping things apart.

On mine it was in the center under the climate controls. Reach up underneath and there should be a huge bundle of labeled wires that'll hang down.

I found the brown wire but the harness 6J4 only has ONE brown wire. Where does it connect to?

Never mind, found it. Brown to brown for the win.

hello, grabbed this photo from Perro above
can someone tell me what the white plug goes to and possibly what the green red wire is for ?
mine is dangling and that wire is severed
thank you for the 6J4 tip as this fixed my horn issue
