Hi all. First post and thanks in advance for your help.
I have been working on issues with an Excursion that my daughter acquired and when it came time to inspect the vehicle I realized the horn did not work. I took the wheel well off to access the horns and discovered they did not work, so I ordered new horns. I hooked up the new horn and it blows continuously, so I disconnected it. The horn fuse does not blow and I can hear the relay clicking when I press the horn on the steering wheel. I saw some discussions about replacing the horn "bladder" in the steering wheel and other discussions on replacing the clockspring and yet others about the horn relay being bad, which requires replacing the entire fuse block as it is built into the 2004 Excursion fuse block.
I removed the horn bladder and cleaned it but that didn't help, so I'm removing it this morning to try to find a replacement part somewhere. If I can't find a replacement then I'll try the repair outlined in another thread on this site "Sticking Horn Contact Fix" to see if that works.
I could just connect an external horn button to pass inspection but I'd like to fix it the right way if possible and I'm not sure which wires to connect into for an external horn as well. What complicates the situation is it appears under the dash that someone had done some rewiring related to the vehicle alarm system (which I don't know if it works or not). I would attach some photos of the wiring under there, but I obviously need to make more posts first. It seems to be a mess and I don't know what they did or why they did it.
If anyone can advise on the wiring or if you have suggestions on the "bladder" fix or how to wire up an external horn button so I can pass inspection, I would be most grateful! It is already past due.
