Sound like a short in the steering column, probably a bad horn contact. Could also be something wrong with your wiring... but probably the contact.

It's the horn contact on the brass ring. Mine does the same exact thing, slightly to the left and it works. Once you pull the wheel off, you'll see it. There is a small piece that's spring loaded that makes contact with the brass ring. You can try to clean it, and even stretch the spring, but it still didn't really fix it for me. I might just break down and get the parts and fix it right. Simple though, and you'll see everything once the wheel is off.

There is an easy fix no parts needed (generic procedure):
1. Remove steering wheel
2. Remove brass ring attached to the back of the steering wheel (three small phillips screws)
3. Reinstall brass ring with three small washers under the ring and tighten the screws.
4. Reinstall steering wheel.
5. Honk the horn till you neighbors complain.

Hope helps.

The horn does not work on my 2006 Avalon XLS, though it works when I hit the panic button. Where is the relay located for the steering wheel horn feature?


If the horn sounds at all, to me, that means the horn relay is ok. The horn relay is in the underhood fuse box.
What you might try is a redundant ground wire from upper steering column support bracket to known good chassis ground.
I saw a service bulletin relating to horn ground on your vehicle, between steering column and chassis. if that is the problem, they have an improved steering column assembly, but, see if the jumper wire will work, first.

I have a 2001 dodge durango. the horn works when i set the alarm but does not work from the steering wheel at all.


The horn has power all of the time but does not go off untill it is grounded. The switch in the steering wheel is the ground when you press it completing the circuit and sounding the horn. The alarm does not use the steering column or steering wheel ground path to "beep" the horn, it uses its own ground. The problem then will more than likely be in the steering column, steering wheel switches, or clock-spring. The clock spring is not for the clock. It is a spiral-wound wire set that allows the steering wheel to turn and not bind up the wires going into the steering wheel. It is called a clock-spring due to the "spiral" wound design of the connector. The horn ground wire in the steering wheel gets its connection through this clock-spring, so it may the source of your problem. It would require some electrical diagnostics to verify the actual point of failure.

Your problem is most likely a defective clockspring assembly. This is also called "spiral cable assembly" it is located just under the steering wheel on the steering column and makes the connection between the main wiring harness and the circuits for the air bag and the horn. I cannot give you wire colors because your question did not mention year, make, model, engine size or whether the vehicle is equipped with cruise control or not. (cruise control makes a difference in the clockspring assembly used on your car.)

Anyway, the air bag and steering wheel has to be removed to fix it.

The horn not workingI


The metal plate in reference above has small copper contacts. If they do not meet the horn will not work. We used a dremel on ALL of the contact point and it made no difference, the horn still only works about 5% of the time. After a whole lot of testing (I have the same issue with my 2000 Toyota Sienna) we found that the ground is weak, too weak for the relay most times. At this point I am going to run an alternate ground by "borrowing" the wire for the mute button for audio controls through the clock spring. The existing ground connects to the steering column. Before we discovered this I spent $285 on a new clock spring :(
