Why Does the Car Horn Suddenly Stop Working?
2 Answers
The reasons why a car horn suddenly stops working are: 1. Insufficient battery power; 2. Damaged horn relay and button; 3. Worn-out horn contacts; 4. Poor internal sealing of the horn, leading to moisture; 5. Poor contact at the electromagnetic coil terminals. The solutions for a suddenly non-working car horn are: 1. Recharge the battery; 2. Repair the horn relay and button; 3. Replace the horn contacts; 4. Clean the horn interior and ensure proper sealing; 5. Check the electromagnetic coil terminals. The car horn is an audio signaling device. During driving, the driver uses it as needed and according to regulations to issue necessary audio signals, warn pedestrians, alert other vehicles, ensure traffic safety, and also for urging movement and conveying signals.
Having driven for over twenty years, I've encountered non-functioning car horns several times. The first step is usually to check the fuse - locate the horn-labeled fuse in the steering wheel's fuse box, gently pull it out to see if the filament is broken. If it's broken, simply replace it with a new fuse, which costs just a few yuan. If the fuse is intact, the issue might be dust accumulation on the steering wheel button; clean the contacts with an alcohol-dipped cotton swab and try again. Wiring problems are also common, especially in older cars where connections may be corroded or loose - a slight tightening often does the trick. If the horn itself is faulty, it needs replacement; it's not expensive but be careful during installation to avoid short circuits. This issue needs prompt attention as a non-functioning horn is particularly dangerous when you need to warn others on highways. I perform weekly simple checks on in-car devices to prevent such failures - don't wait for an accident to regret it.
