"Money can't buy happiness -- but somehow it's more comforting to cry in a CORVETTE than in a Kia"

Thanks, That sure looks to be the problem.

The orange(or red) is from the fuse box.
The green goes to the horn(s)
Black goes to the horn button, and provides the ground for the relay. If you jumper the green & orange(red) wires(with the relay unplugged), the horn(s) should sound. Assuming, of course, that the fuse is good, and the relay has power to it on the orange(red) wire....and that the horn(s) works.
With it all plugged in, you can ground the black wire, and see if the relay clicks/horn sounds. If it does, your problem is in the black wire from the horn button.
If you have an ohm-meter, you can check the horn button there, also. Black lead to a good ground, red lead to the black wire on the relay connector. There should be no continuity until you press the horn button.

Man Jeff, it really sucks when you can't blow your own horn.

I just had this problem occur yesterday, but the cause is a question. When I flipped up the tilt wheel on my 78 the horn went off and would not stop until I lowered the tilt wheel to the lowest point. Now it will not sound at all.

Dammit....I just spent 20 minutes typing a response, hit "Post", and the dam thing went back to the topic page, without posting....

Anyway...long story short, John....the problem is most likely a break in the wiring in the column. Witht he tilt wheel, the wiring bends, and over time, can cause breaks in the wires, and sometimes the wires will short. If it happens to be the horn ground wire that shorts, the horn will toot until the wire is moved, and contact is lost. Sounds like you're going to be digging into the column. You might be able to find/repair the wiring. If not, you might wind up replacing the turn signal switch.
Would be worth removing the steering wheel and having a look, to make sure it is nothing simple on the top end, but your description of the problem points to a wiring break.

I did replace my horn relay and got all excited when I got my first toot, but not much after that. Hit it just right and once in a while it works. looks like I gotta start checking under the button too.

Jeff, sort of make's sense as you had no brake lights at eboland!

Got that figured out. Pulled the plug on the brake light switch, crossed the connection and shazam, Brake lights. Got a new switch coming.
