When the horn button is pressed on the steering wheel or position, the current from the will flow through the loop to the electromagnetic coil of the horn relay. When the electromagnetic coil draws the relay moving contact switch to close, the current will flow to the horn. The electric current causes the electromagnet inside the horn to work, causing the membrane to vibrate and produce sound.
- In many of the problems with the speaker, the problem is usually the fault of the speaker itself. In particular, there are some defects in the installation position of horn designed by some cars. When it , it is easy to make the horn get wet by rain, causing damage to the horn. You can refer to the following steps when a failure occurs.Sometimes does not ring the horn switch, if the horn sometimes ring, sometimes does not ring, is the horn switch internal contact is not good, some is also the horn itself problem.

- First check the fuse to see if it fuses, then unplug the horn plug and use a multimeter to measure whether there is electricity when the horn switch is pressed. If there is no electricity, check the horn harness and relay. If there is electricity, it is a problem of the horn itself. At this time, you can also try to adjust the adjusting nut on the horn to see if it can sound. If it still doesn't sound, you need to replace the horn.
