Why does the car horn suddenly stop working on rainy days?

[MacEvangeline]

This situation may not be closely related to rainy weather. It is more likely that the horn itself has malfunctioned. In fact, a faulty horn should not be taken lightly. During vehicle operation, drivers rely on the horn to emit necessary sound signals as required by regulations, warning pedestrians and alerting other vehicles to ensure traffic safety. It is also used for urging and signaling. More relevant information is as follows: Note 1: If the horn only occasionally fails to sound, it is mostly due to poor contact of the internal switch contacts, or sometimes the horn itself is the issue. If the horn does not sound at all, first check if the fuse is blown, then unplug the horn connector and use a multimeter to measure whether there is electricity when the horn switch is pressed. Note 2: If there is no electricity, inspect the horn wiring harness and horn relay. If there is electricity, the problem lies with the horn itself. At this point, you can also try adjusting the adjusting nut on the horn to see if it can produce sound. If it still does not work, the horn needs to be replaced. Regardless of the method, please promptly visit a repair shop or 4S store for inspection and repair to ensure driving safety in the future.
