Why doesn't the car horn sound?
2 Answers
The reasons why a car horn doesn't sound are as follows: 1. Horn damage: If the car's horn has been used for too long, the reason it doesn't sound may be due to damage, in which case it needs to be replaced at a repair shop. 2. Water ingress: If the car's horn gets water inside, especially during car washing, extra attention is needed. Once water enters, drying treatment should be performed. 3. Circuit fault: If there's a short circuit in the car's electrical system, it can also cause the horn not to sound, requiring circuit troubleshooting. 4. Horn contacts: If the horn contacts are not sensitive, it can also lead to the horn not sounding, necessitating corresponding adjustments.
Honestly, it's really frustrating when the car horn suddenly goes mute. Last time I encountered this issue, I found it usually boils down to a few common problems: Most likely, it's a poor contact in the horn button on the steering wheel – older cars tend to accumulate dust or wear out inside the button over time. Another possibility is a blown fuse; just look for the small tab labeled "HORN" in the engine bay or the fuse box near the driver's seat, and replacing it costs just a few bucks. The horn itself could also be faulty – it's usually located near the radiator in the front of the car. You can test it by touching the horn's terminals with a screwdriver to see if it sounds. If there's no response, chances are you'll need a new horn. It's also common for front wiring to degrade or get chewed by rodents, so you might need to check under the car. Oh, and for older cars with a horn relay, that little black box could be the culprit too. If you can't figure it out yourself, it's best to take it to a mechanic ASAP – driving without a horn is just too risky.
