Faulty Horn Honk

Why does my horn honk intermittently when I turn the steering wheel? It happens when I am turning sharp in reverse or forward at low speed such as backing out of my garage.

Could be the spring loaded contact under the steering.

Spring Under Steering Wheel

Thanks Vince.

Please explain why and how it could be the spring under the steering wheel and what the possible fix may be.

Is it a GM column? Has the turn signal lever been replaced recently?

I had the same problem on a street rod when I put cruise control on it. It had the style of GM turn signal lever that attaches to the switch with a screw and the lever seated in a tapered slot. The new turn signal switch lever I installed was too wide at the base to fit in the tapered slot. Which caused a problem EXACTLY like you are describing.

The solution was to take the wheel back off, remove the TSS lever and grind the tapered edges down until it would fit properly. I have also had the same problem with every turn signal lever of this style I have replaced in the last five years. It seems to be a problem the manufacturer is either unaware of, or more likely, unconcerned with.

Otherwise, it could be that the horn wire in the column is worn bare and rubbing on the steering shaft under certain conditions. Could be a lot of things, I guess.....

Hope this helps.

Joe G.

faulty horn.

Hey Joe.
Yes. it is an Ididit column GM style.
You mention the horn wire possibly being worn bare...... It is actually totally exposed with no insulation. What should the spring look like?

Faulty Horn

Joe. Thanks...looks just like mine.
Question..... is the spring a conductor and could it be touching metal as the wheel turns? ..... for something so simple I am at a loss for what the springs function actually is......

The spring in the horn brush tube (about the diameter of a pencil) is hot. It triggers the horn relay when it gets grounded. On a stock GM steering wheel, the function of the spring is to hold the horn brush against the horn button mechanism on the back of the wheel. On aftermarket steering wheels, there is usually a wire that connects from inside the tube to a spade connector on the back of the horn button.

Is any of this helping? Or are you talking about a different spring?

That is an excellent explanation Joe. Probably what has happened is the little barbed piece that you push in and turn to lock in the spring loaded button has gotten buggered.

Faulty Horn.

Thanks Joe...... so maybe when the steering wheel is turning the spring is touching when it shouldn't?..... what if I insulate (tape)...the spring except for the very top where it touches the steering wheel when the horn button is pushed?.....By the way...it is an aftermarket steering wheel.

The spring should not be protruding from the tube. If it is, there is something missing, or buggered, like Vince said. With an aftermarket steering wheel, I would expect to see a wire like this one connected to the horn contact tube:


Here is what it looks like installed, before the steering wheel adapter is installed:


The black tube around the wire extends through the un-threaded hole in the steering wheel adapter, and the spade terminal connects to the back of the horn button.


If it has a GM style steering wheel, there should be a solid metal contact pin, a spring, and a plastic 1/4 turn retainer in the horn contact tube, which should be assembled as shown in this video:

Hope this answers your question.

Hey Joe. I just wanted to let you know that your suggestion worked. The turn signal screw head was to tall and touching the horn hot circuit when I turned the wheel..... I ground it down and no more horn honk. It has been since November 08 that you recommended that fix and I just got around to it yesterday......just in time for the street rodding season. Thanks again.
Doug
