Why does the car horn keep sounding?
2 Answers
The reasons why the car horn keeps sounding are: 1. The horn button on the steering wheel is stuck and remains in the position of continuous power supply. 2. The relay contacts are stuck together and cannot disconnect normally, leading to continuous contact. 3. The negative switch wire of the horn is grounded. Relevant information about car horns is as follows: 1. Horn: It is the audio signal device of the car. 2. Function: During the driving process, the driver can issue necessary audio signals as needed and required to warn pedestrians and attract the attention of other vehicles, ensuring traffic safety. It is also used for urging and transmitting signals. 3. Working principle: The car electric horn produces sound through the vibration of a metal diaphragm. 4. Composition: The car electric horn consists of an iron core, magnetic coil, contacts, armature, diaphragm, etc.
I've been driving for years, and recently my car horn suddenly started blaring non-stop, alarming the entire neighborhood. Upon inspection, I found that the horn button on the steering wheel was stuck and wouldn't pop back up, likely due to water ingress or long-term wear and tear from pressing. If the horn keeps sounding, first try pressing the button rapidly a few times to see if it resets. If that doesn't work, you'll need to check for any short circuits in the wiring or a burnt-out relay. This is a fairly common issue, especially in older cars, and if left unaddressed, it can drain the battery, leaving you stranded on the road. I think it's important to avoid getting water on the steering wheel when washing the car and to regularly maintain and inspect the switch components as a preventive measure. If you can't fix it yourself, it's best to take it to a reliable auto repair shop immediately—safety first.
