Fohveh, don't know if you ever found the issue with this. When I replaced my relay, I could easily see at least one of the wires running to the horns, I believe it was the black/brown(orange/red?) striped wire. You could easily check to see if that wire has a break in it.Oh yeah, I replaced the ignition switch as well. Still no horn.The wires are part of a massive wire bundle in the dash so it is very hard to go through. I'll likely find the beginning to it and run clean new line to the horns and simply bypass the faulty horn lines in the bundle.
