The horn is an important component for a car. They not only serve as a means of communication on the road, but also safety markers. The sound alerts other road users to the presence of our vehicle. Especially in emergency situations or areas with low visibility. However, in some cases, car horn not working often occurs.

Trigger Factors for a Car Horn Not Working and How to Fix It
It must be noted that a horn that is not functioning optimally can have various negative impacts. Both for the driver and other road users. For example, without a horn, the driver will have difficulty giving warnings to vehicles or pedestrians when in an emergency situation.
This can increase the risk of accidents. Especially on busy roads. In addition, the horn is an effective non-verbal communication tool on the road. With the horn not functioning, communication between road users is limited. Thus increasing the potential for misunderstandings and the risk of conflict.
So why can the horn suddenly not sound? Basically, there are several causes that generally make the car horn not work. However, before that, in the experiment on the Auto Repair Guys YouTube channel, it is necessary to first check the horn components.
Make sure to remove it from the car, then connect it to a separate power source. If the horn sounds normal, then the damage may be in the supporting device. Some of them include:
1. Damaged Fuse
The first cause is damage to the fuse. This component functions as a safety device that protects the vehicle’s electricity, including the horn, from excessive current. If the fuse breaks, the electric current to the horn will also be cut off.
To fix it, of course, you need to check the condition of the fuse first. If the fuse breaks, replace it with a product that has the appropriate ampere capacity.
2. Problematic Horn Button
A damaged or dirty button can cause the horn to not work. This problem usually occurs due to wear or dust accumulation on the bottom of the button. If the problem is with the button, open the steering wheel and clean the dust and dirt. Use a dry, clean cloth so that the cleaning process is optimal.
3. Broken or Loose Cable
A broken or loose cable can inhibit the electric current to the car horn, making it not work. This often occurs due to corrosion or poor installation. Check all cables connected to the horn. If there are any disconnected or loose cables, reconnect them properly. Always remember to use electrical insulation to protect the connection.
4. Relay Problems
For your information, a relay is a component that helps flow electric current to the horn. Usually, the relay is located near the fuse box. If the relay is problematic, the electric current will not reach. Therefore, check carefully and replace it if the component is no longer possible. On the market, the price of a relay varies from tens to hundreds of thousands depending on the specifications.
5. Weak Battery
Finally, a weak battery can also be a trigger for the car horn not working. The reason is, the horn requires electrical power from the battery to function. If the battery is weak, the horn will not make a sound normally. Like too small, intermittent or not sounding at all. Make sure the battery is in good condition and has enough power. If it is weak, recharge it or replace it with a new battery.
By understanding the causes of the car horn not working and how to fix it, you can take early action. So there is no need to rush to take it to the repair shop. However, if you have done the above method and the horn is still dead, make sure to contact a professional technician immediately. In addition, try to always do routine maintenance on the vehicle so that the trip remains safe and comfortable.
