Snail horn is a common type of horn that is often used in various vehicles, and many cars also use this type of horn. However, I believe everyone has noticed a problem when using it, which is that it sometimes does not sound. In fact, it is not only the snail horn that has this fault, but other horns may also have it. Today, the editor will focus on the solution to the problem of snail horn not sounding.

Based on the author's experience, in many cases of speaker malfunctions, the problem often arises from the speaker itself. Especially in some designs, there are defects in the installation position of the horn, which can easily cause damage to the horn when it rains. When the horn does not sound, there are three common faulty parts, namely the snail horn itself, the horn switch contacts, and the horn harness. When a fault occurs, you can refer to the following steps for inspection.
(1) Sometimes it doesn't sound. Pressing the horn switch, if the horn sometimes rings and sometimes does not, it is mostly due to poor contact between the internal contacts of the horn switch, and some are also problems with the horn itself.
(2) His voice is hoarse. This is mostly due to poor contact of the plug, especially the various contacts around the steering wheel, which are prone to wear and tear due to frequent use.
(3) Completely silent. Firstly, check if the fuse is blown, then unplug the horn plug and use a multimeter to measure if there is power at this point when pressing the horn switch. If there is no electricity, check the horn harness and horn relay; If there is electricity, it is a problem with the horn itself. At this time, you can also try adjusting the adjusting nut on the horn to see if it can produce sound. If it still does not produce sound, the horn needs to be replaced.
Maintenance content of snail horn:
1、 Car audio speakers often check the output voltage of the generator. High voltage can burn out the horn contacts, while low voltage (below the rated voltage of the horn) will cause the horn to produce abnormal sounds.
2、 Do not put any foreign objects into the speaker to avoid causing abnormal sounds.
Regularly check and tighten the fixing screws of the horn and bracket to ensure reliable grounding.
3、 The continuous pronunciation of the horn should not exceed 10 seconds to avoid damaging the horn.
4、 Regularly keep the appearance of the horn clean and ensure that all wiring is secure.
5、 When washing the car, do not rinse the horn directly with water to prevent water from entering the horn and causing it to not sound.
6、 When repairing the horn, attention should be paid to the position of each metal pad and insulation pad, and they should not be installed incorrectly.
7、 The method of fixing the horn has a significant impact on its pronunciation. In order to ensure the normal sound of the horn, it cannot be rigidly installed, so it is fixed on a buffer bracket, that is, a sheet-like spring or rubber pad should be installed between the horn and the fixed bracket
8、 Regularly check and tighten the fixing screws of the horn and bracket to ensure reliable grounding.
