The other day, there was this m*r*n in front of me so I was compelled to use my horn. Much to my surprise, nothing happened when I hit the center of the steering wheel.
So I checked the horn fuse in the relay center, and it was blown. I got a new one and when I inserted it, the horns sounded for a fraction of a second and the fuse blew again.

So obviously, there are two things wrong here:
First, the horns should not sound without touching the horn switch.
Second, the fuse should not blow when the horns sound.

I went ahead and removed the horn relay and checked it. It seems to be fine. Also, without the relay in place, the fuse did not blow.
Then I unplugged all four horns and inserted the relay again. The fuse did not blow.
I plugged in one horn and it sounded immediately, but the fuse did not blow.
I haven't checked each horn individually yet, but I guess one of them must be bad and cause a short circuit.
So far so good. That was the easy part.

Now, why do the horns sound without touching the horn button? My guess is that the switch in the steering wheel is bad somehow. I'd like to disassemble the wheel and take a look, but with the airbag and all, I'm a little hesitant.
And I did not find the horn switches as individual replacement part. Does that mean the entire airbag assembly needs to be replaced? Is it even possible to repair a horn switch?

Thanks for any information.

HotZ28, that's great information, thanks! :thumbsup:

So, there are two horn switches. I guess there is a chance that only one is bad and unplugging the bad one would solve my problem.

:)That is a possibility, but as the old saying goes "When one goes bad, the other is not far behind". :iceslolan Just remember, when working in this area, be sure to disconnect the negative battery cable first, then the positive and touch the two together, in order to drain any residual power. BTW, you are correct, the switches are an integral part of the air bag assembly and they can not be replaced without replacing the whole unit. :rolleyes:

I hope that one of the switches still works fine and I can save the idea of drilling a hole and mounting a button for later... :)

I'll keep posting any updates.
