Car horn common fault treatment

The car horn is a device that is frequently used when driving, and if the horn fails, it will be very inconvenient when driving.

Let’s first look at how the horn works. When the horn button on the steering wheel or elsewhere is pressed, the current from the battery flows through the loop to the electromagnetic coil of the horn relay, which attracts the moving contact switch of the relay to close, and the current flows to the horn. The electric current makes the electromagnet inside the horn work, which causes the vibrating film to vibrate and make a sound.

In many loudspeaker failures, the problem is often the fault of the loudspeaker itself. In particular, there are defects in the horn installation position of some car designs, and it is easy to make the horn wet by rain when it rains, causing damage to the horn. When a fault occurs, refer to the following steps to check it.

Sometimes the horn switch does not ring, if the horn sometimes rings, sometimes does not ring, mostly the contact inside the horn switch is not good, and some are also the problem of the horn itself.

The hoarse sound is mostly due to poor plug contact, especially the various contacts around the steering disc, due to frequent use, it is easy to wear the contacts.

First check the fuse to see whether it is blown, and then unplug the horn plug, use a multimeter to measure whether there is electricity when the horn switch is sounded. If there is no power, check the horn harness and horn relay; If there is electricity, it is the problem of the horn itself, at this time you can also try to adjust the adjustment nut on the horn to see whether it can sound, if it still does not ring, you need to replace the horn.
