Why does the car horn sometimes work and sometimes not?

[DiKeira]

Reasons why the car horn sometimes works and sometimes not: Poor contact of the internal contacts in the horn switch, which intermittently causes this situation. Some issues may also stem from the horn itself. According to the working principle of the horn, once the contacts have poor connection, the phenomenon of the horn sometimes working and sometimes not occurs. When encountering this situation, the first consideration should be whether the contacts are wet, damp, or affected by other factors. Sometimes, the contacts around the steering wheel may wear out due to frequent use, leading to poor connection, which can also cause the horn sound to become hoarse. If this happens during rainy weather, combined with poor contact, it is very likely that the sound will become lower or even disappear.
