Where is the horn switch connected?
Car horn switches, or buttons, are typically mounted in the steering wheel. Some steering wheel buttons are mounted off to the side of the steering wheel, but most are located directly in the middle of the wheel. Most horn switches are normally open, which means they only close when the button is pressed.

How does horn switch work?
The horn button is located on the steering wheel. Its purpose is to sound the horn when pressed. However, the horn takes many amps of current, more than the wires from the button switch can handle, so instead the button completes an electrical circuit allowing a small amount of current to flow in a horn relay coil.
What does the horn circuit include?
The circuit has three main components: the horns themselves, a relay (mounted low on the right side inner fender, well forward) and the horn push contact in the steering wheel pad. The horns are always grounded and rely on voltage from the relay to operate.
How much is it to replace a horn switch?

How do you shut off a jammed car horn?
To shut off a jammed horn, first try pushing the horn and twisting the steering wheel a few times. If that doesn’t work, disconnect the car battery to silence the horn. Should the problem recur when you reconnect the battery, disconnect the fuse connected to the horn and remove the horn relay.
Where is the fuse on the car horn?
Disconnect the horn itself. If your car has no relay and the horn’s fuse is on the same circuit as other important components, remove the horn itself. This is located under the hood, usually behind the front grille or attached to the firewall behind the engine.
What causes a car horn to not shut off?
A horn that won’t shut off is usually the result of a jammed mechanical component in the steering column. Examining this area requires some caution due to the airbag located here, so it’s easiest to start by disconnecting power from the horn and testing the more accessible parts of the system.
What causes a horn switch to be jammed?
Replace the switch or clock spring. If the electrical parts are all functional, the horn switch under the steering wheel may be jammed. Another possibility is a broken clock spring: the coil that winds and unwinds as you turn the wheel to maintain the electrical connection.
