“My car horn sounds weak and has been getting quieter over time. Why does it happen? Is there any way to fix the problem?”
A car horn is an essential element in a car’s signal system. A car horn is used to pass a “message” to other cars on the road, just like a signal light.
However, your car horn can become weak after a period of use. As such – you may find the sound becomes weaker. A weak sound horn can be the source of accidents and unsafe traffic.
In this article, let us share the root cause of a weak horn sound and how to fix it.
Why is a car horn sounds weak?
Every car part has its lifespan. A car horn can last from 6 to 10 years. However, it depends on the usage condition.
How do you know the horn needs a replacement? You can notice when the car horn is not working and produce a low tone.
What causes a horn turns weak?
Check the fuse box to see if the fuse for the horn has blown. You may either find it on the inside of the car’s panel or under the hood.
The fuse box may be faulty due to – damaged wiring or a short circuit. The blown fuse may hinder the electric power to go through, thus causing the horn to produce a quiet sound.
If you are unsure, you can refer to the manual to find the location of your fuse box.
Broken clock spring
When the clock spring breaks, it can cause the horn to sound muted or even fail to sound at all. In some cases, a broken clock spring may also cause the horn to sound intermittent.
If you suspect that the clock spring is the problem, it is important to repair it immediately. In addition to preventing your car horn from sounding correct, a faulty clock spring can also pose a safety hazard.
The reason for a horn sounding weak can come from the wiring system. If the wiring is either old or loose, it may not be able to carry enough electricity to power the horn.
Last but not least, the reason why your horn is not working may be caused by the horn itself being damaged.
If the horn has been hit or crumpled, it may not be able to produce a strong sound.
How to tune a weak car horn?
There are several simple steps you can take to repair it.
- Check out the fuse box to see if the fuse for the horn has been damaged. If it is blown, replace the fuse with a new one
- Check the horn relay and try swapping the horn relay with a replacement relay
- Inspect the circuit and source grounding for current and voltage.
Whatever the problem is, there are many potential solutions for fixing a car horn. A car horn can be repaired relatively easily. However, the exact steps may vary depending on the type of horn and the extent of the damage.
If the problem cannot be easily fixed, it is best to consult a qualified mechanic.
