You more than likely have an intermittent short in the wire that goes from the horn to the fuse panel inside the interior. That wire should be green/orange, if I remember correctly. If you trace that wire and find no shorting out with other wires, check the actual horn button on the steering wheel. The front padded section of the horn can be removed by using a small phillips screwdriver to remove the two small screws securing the horn button to the steering column. There is one on each side of the plastic cover on the back of the steering wheel. After removing the screws, pull firmly on the front cover and it should pop off with little difficulty. Check inside the column and make sure your horn button isn't making any contact with the metal plate underneath the horn pad. If it is making contact, then that's your problem, if not, your problem is most definitely wiring related.

I Have a 1987 Plymouth Horizon. When i disconected the Battery the horn started blowing and the only way to stop it was to disconect it. If i reconnect it it is still stuck on. Anybody else ever have this kind of problem ?

You might have a short in your steering wheel right underthe faceplate. The metal screws on my Horizon were shorting the circut and causing it to blow. I just took the screws out, or you could get plasic screws. That or unplug the horn fuse under the dash on the driver's side.

I had a similar problem with my 1988 Plymouth Reliant. The horn starts blowing when the sun shines on the horn pad and heats it. If I cover the horn, it shades it and the horn doesn't blow. I took the horn pad off (See Roofy's message) and found that the metal network makes contact when pressed (which happens when you blow the horn normally). But now that contact is made from the sun's heat. I tried to prevent this by bending the metal network back, but it still shorts from the sun. So I have just disconnected the horn, which is not wise. So - I need a horn pad replacement, but can't find one. Where can I get one - a new one??

Do NOT unplug the fuse as Tim E. suggested. That fuse also controls the power flow to your tail lights and you will get pulled over if you remove the fuse.
