What is the reason why the car horn is pressed and sometimes the horn does not stop

Combined with factors such as the environment, the failure of the speaker itself is mainly due to the following reasons:

1.Contact ablation: If the horn is pressed for a long time, it is easy to cause the horn contact to be ablated and the impedance will be generated, the current flowing through the electromagnetic coil will be weakened, and the electromagnetic attraction will not be able to attract the armature to drive the diaphragm to vibrate normally, resulting in hoarse or even no sound.

However, when the horn is constantly pressed, if the instantaneous strong current passes through the impedance, it can still work normally, so it will be good and bad.

2.Loose sealing is susceptible to moisture: Although the inside of the horn is sealed, if the seal is not tight, if it enters the fog or there is water vapor in the air in the internal space when washing the car, the water vapor can easily cause the contacts to be damp and unable to work properly.

3.Poor contact of solenoid terminals: some horns inside the electromagnetic coil enameled wire terminal joint is connected by aluminum metal rivet crimping, non-reliable soldering connection, if the insulating paint on the enameled wire at the end is not clean or the rivet crimping is not reliable, it is easy to produce virtual connection faults, resulting in poor horn work.

This kind of failure is the quality of the horn, which cannot be repaired, and can only be replaced with new parts.

Precautions in the use of car horns:

1.When washing the car, remember to prevent the horn from getting wet, and dry it with an air gun as soon as possible if you find water from entering the horn.

2.Try not to always press the horn for a long time, which can easily cause premature ablation of the horn contacts.

3.If the horn fails, try to seek the help of a professional maintenance technician, and do not blindly replace the horn, which is easy to cause unnecessary waves. Fee.

Hello, it is recommended that you check the horn relay.

It could be that the horn itself is faulty, or it could be that the steering wheel horn contacts are ablated due to poor contact.

The horn relay, or the horn switch is not popping up.

Hello owner, this is the horn switch on the steering wheel, this gap is small, and it needs to be adjusted. I hope mine is helpful to you, if you still have questions, you can continue to consult me, I wish you a happy life and good luck. --Car Master is at your service
