Common troubleshooting of car horns

Let's first take a look at how the speaker works. When the horn button on the steering wheel or other positions is pressed, the current from the battery will flow to the electromagnetic coil of the horn relay through the loop. The electromagnetic coil attracts the movable contact switch of the relay to close, and the current will flow to the horn. The electric current makes the electromagnet inside the horn work, so that the diaphragm vibrates and produces sound.
In many horn-related failures, when the problem occurs, it is often the failure of the horn itself. In particular, the installation position of the horn designed for some automobiles has defects, and it is easy to get the horn wet by rain when it rains, causing damage to the horn. When a fault occurs, you can refer to the following steps to check.
Sometimes the horn switch is not sounded. If the horn sounds sometimes and sometimes does not sound, it is mostly because the contacts inside the horn switch are not in good contact, and some are also the problem of the horn itself.
The hoarse sound is mostly due to poor contact of the plug, especially the contacts around the steering wheel. Due to frequent use, the contacts are easily worn out.
No sound at all. First check the fuse to see if it is blown, then unplug the horn, use a multimeter to measure whether there is electricity when pressing the horn switch. If there is no electricity, check the horn harness and horn relay; if there is electricity, it is the problem of the horn itself. At this time, you can also try to adjust the adjustment nut on the horn to see if it can sound. If it still does not sound, you need to replace the horn.
