Horn problem
-New to Forum
Here's a puzzler!
Recently noticed that horn (activated by pushing center of steering wheel) does not work in 1998 4cyl auto EX Accord when engine is running. However, it does work if engine is off with key out!
Swapped horn relay with no change. Car is stock except for remote stater but that was added 7 years ago and no problem until now.
Anyone with a guess to problem solving before resorting to dealer?

I think the horns are self-grounded. IOW there's only one wire (hot). .

RE: Horn problem
So the horn trigger circuit has to go thru the cable reel at the steering wheel, to the horn button. Anything in there that would know or care whether the engine's running?
The horn switch simply connects that triggercircuit to ground. The alarm also can connect it to ground, so that doesn't seem like it should be able to interfere.
There's a branch of that circuit off to the multiplexer, but that too shouldn't be able to interfere with the horn button.
