What makes a horn work in the steering wheel?
As the steering wheel rotates these are in constant contact by spring pressure. When the horn switch is pressed, it completes a circuit to ground and causes the horn relay to send current to the horn/ horns.
The horn in the steering wheel works through a combination of electrical and mechanical components. When you press the horn button on the steering wheel, it completes an electrical circuit that activates the horn relay. The relay, in turn, sends power from the car’s battery to the horn, causing it to emit a sound. Inside the steering wheel, there’s a contact ring known as a “clock spring” or “slip ring.” This component allows electrical signals to pass between the stationary part of the steering column and the rotating steering wheel. When you press the horn button, it sends a signal through the clock spring to the horn relay, initiating the horn’s operation. Additionally, there’s a horn switch or button located within the steering wheel assembly. When you press this button, it makes contact with the clock spring, completing the circuit and activating the horn relay.
Why does my horn honk when I turn my steering wheel?
It’s pretty obvious you’ve got a loose, damaged (and possibly shorted) wire either at the horn or actuator itself, or somewhere in the steering column. The symptoms match that perfectly. Unless you’re a mechanic yourself, take your car to one. Cheers.
If your horn honks unexpectedly when you turn your steering wheel, the issue likely stems from a fault in the clock spring or slip ring within the steering wheel assembly. The clock spring is responsible for allowing electrical signals to pass between the stationary part of the steering column and the rotating steering wheel.
