I've got a '98 Accord with a really weird problem. The horn is
intermittent while driving (it doesn't work when the steering wheel is
centered, only when turning). When the engine is shut down, and the
key removed, it works perfectly, no longer intermittent. When removing
the key, it's after the very last "click" that the horn starts working
correctly. First, I tried replacing the cable reel assembly, which
didn't make any difference.

Now I'm trying to troubleshoot the circuit, but my dumb Haynes manual
doesn't have anything in the schematics for the horn. Does anyone know
what the source is of the signal for the horn? There's one wire coming
out of the airbag assembly (where the horn switch is), and it has a
ground when the switch is pressed. Which ends up actuating the relay,
etc. But where does that ground come from? I think that's where my
solution lies. I thought the ground might come from the SRS wires, but
nothing changed after disconnecting them. Same with the ignition
switch.

I just can't understand why the ignition switch would have anything to
do with this problem, since the horn should always be hot!

Any suggestions or ideas would be welcome!
