What s the matter if the horn of a Chery car doesn t sound?

Chery. The horn does not sound generally due to the horn fuse.

Burned out, insufficient battery storage, horn relay and button damage, horn damage, etc., need to replace the fuse and other related accessories. Although the inside of the horn is airtight, if the seal is not tight, it enters the fog or the internal space when washing the car, and there is water vapor in the air.

Knowing water vapor can easily cause the contacts to be damp and not work properly.

You can check the power system. Turn on the headlights.

Switch, the headlamp is not lit or dim, start the engine at this time, slightly increase the throttle, if the headlamp light is normal, the horn sounds, it is the battery storage is insufficient, the battery and its connection cable should be checked according to the above method. In the case of insufficient battery storage, the car can drive normally, and when you need to honk the horn, you only need to increase the throttle appropriately;

If the brightness of the headlamp is normal, press the horn button system, check whether the relay has a click, click, rattle, if there is, it may be that the horn is damaged or the horn is faulty, the horn assembly should be replaced or the fault of the horn is eliminated. The horn relay is usually located at the bottom left of the steering wheel, please refer to the on-board instruction manual and the fuse on the car for the position of the horn relay of different models.

Relay identification plates, horns are usually located behind the radiator (water tank). If the horn is bad, the horn can be removed and reinstalled; If the horn is damaged, it will need to be replaced with a new one.

Hope to be you.

1.Loose sealing is susceptible to moisture: Although the inside of the horn is sealed, if the seal is not tight, if it enters the fog or there is water vapor in the air in the internal space when washing the car, the water vapor can easily cause the contacts to be damp and unable to work properly.

2.Poor contact of solenoid terminals: some horns inside the electromagnetic coil enameled wire terminal joint is connected by aluminum metal rivet crimping, non-reliable soldering connection, if the insulating paint on the enameled wire at the end is not clean or the rivet crimping is not reliable, it is easy to produce virtual connection faults, resulting in poor horn work.

This kind of failure is the quality of the horn, which cannot be repaired, and can only be replaced with new parts.

3.Contact ablation: If the horn is pressed for a long time, it is easy to cause the horn contact to be ablated and the impedance will be generated, the current flowing through the electromagnetic coil will be weakened, and the electromagnetic attraction will not be able to attract the armature to drive the diaphragm to vibrate normally, resulting in hoarse or even no sound.

However, when the horn is constantly pressed, if the instantaneous strong current passes through the impedance, it can still work normally, so it will be good and bad.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

1. Contact ablation:If the horn is honked for a long time, it is easy to cause the horn contacts to be ablated, and a certain impedance will be generated, so that the current flowing through the electromagnetic coil will be weakened (the electromagnetic attraction will be reduced). At this time, it is definitely impossible to attract the armature to drive the diaphragm to vibrate normally, and it is also possible that the horn is hoarse, or even not sound.

2. Moisture caused by poor sealingWhen you need to clean the interior, you have to pay attention to the position of the horn, do not let some water vapor into the horn, otherwise it will cause the horn to be damp, not only directly affect the sound effect of the horn, but also the phenomenon that the horn does not sound in serious cases.

Precautions for using horns.

1. It is recommended to use a horn prompt at no signal and unattended intersection, up to three sounds.

2. Mountain roads, curves, and dead corners (intersections without auxiliary mirrors) are recommended to use horn prompts, up to three sounds.

3. When overtaking at high speed, use the horn with the lights to remind the vehicles in the next lane.

4. When prompting a problem vehicle on the road (insufficient tire pressure, serious deviation, door not closed, etc.), it is recommended to use lights to prompt it first, and if there is no effect, it is best to inform the other party of the vehicle in the stop state.

1. Check the sound of the horn, if you feel that the sound is not crisp, low and weak, most of the contact is poor.

2. Press the switch of the horn repeatedly, if the horn sometimes rings, sometimes it does not sound, most of the contacts inside the switch are not in good contact.

3. Turn the steering wheel left and right, if there is a larger one"Sizzle"Friction sound, some grease can be sprayed into the relevant contact parts.

First, check whether there is electricity in the live wire. Use a screw to scrape the horn relay "battery" binding post with the grounding iron. If there is no spark, it means that there is an open circuit in the live wire, and whether there is an open circuit between the battery fuse and the "battery" binding post of the horn relay should be checked.

Second, if there is electricity in the live wire, then use a screw to short-circuit the two binding posts of the "battery" and "horn" of the horn relay, if the horn still does not sound, it means that the horn is faulty; If the horn sounds, it means that the horn relay or button is faulty.

Third, press the horn button and listen for any sound in the relay. If there is a "rattling" sound (contact closing) but the horn does not sound, it means that the relay contacts are oxidized or ablated. If there is no "gurgling" sound reaction in the relay, then use a screw to short-connect the horn button binding post with the grounding lap iron, if the relay contact is closed and the horn sounds, it means that the button is oxidized, rusted or dirty and has poor contact; If the relay contacts still do not close and the horn still does not sound, it means that there is an open circuit in the relay coil.

Fourth, press the button, the horn only makes a "ho" sound and then does not sound, this fault is inside the horn, you can remove the horn cover and then press the button to observe whether the horn contact is open. If it can't be opened, it should be readjusted; If it can be opened, check the contact gap and whether the capacitor or arc extinguishing resistor is short-circuited.

Fifth, if the horn does not sound when the button is pressed, check the circuit and find that the fuse jumps (or the fuse blows), first of all, check whether there is a short circuit fault such as a tie in the circuit. The method is to string a test lamp at both ends of the disconnected fuse, if the test light is on, there is an iron place in the circuit from the fuse to the horn relay; If the test light is not on, you can press the button again, if the test light is on again at this time, there is an iron tie in the circuit from the relay to the electric horn, and then use the circuit breaker method to find the tie iron part for investigation.

If the fuse is broken, or the contact point of the horn is not in good contact, it can be reused after disassembling it with yarn paper.

If it's troublesome, just change it.

Where the steering wheel is connected to the body, there is a rotatable disc with wires connecting the airbag and the horn button. After a long period of use, breakpoints may occur, which is normal, but the parts are very expensive. Hope to adopt.

There are 3 possibilities: one is that the speaker itself is broken and does not work. The second is that the contact points of the balance spring of the steering wheel are not in good contact (not very likely). The third is that the fuse is blown (the probability is not great).

There are several failures that affect this failure.

1. The horn itself is broken, and the internal coil is burned out due to water ingress.

2. The line is corroded, the plug is corroded, and the line is connected or broken.

3. The horn relay is damaged.

4 hairspring under the steering wheel.

5. The steering wheel horn switch is not good for iron.

Hope it helps.

Hello, what kind of model is yours, the general horn does not sound is a problem with the fuse, but what kind of symptoms need to be checked, I hope my answer will be helpful to you [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Go elsewhere to see, generally insurance, horns, line problems.

If the horn relay is broken, it can be replaced.

The car horn didn't sound, and I went to the 4S store to say that the bag was broken, and I needed to order the goods, and wait for a few days, so can I drive normally.

For those of you who have rats at home, I'll teach you a good way to get rid of mice.

The Accord horn does not sound, and the horn is installed in **.

There are 3 possibilities: one is that the speaker itself is broken and does not work. The second is that the contact points of the balance spring of the steering wheel are not in good contact (not very likely). The third is that the fuse is blown (the probability is not great).

1.Contact ablation.

2.Loose sealing is susceptible to moisture.

3.Poor contact of solenoid terminals.

Chery QQ horn does not work normally because the horn fuse is blown out, the battery is insufficient, the horn relay and button are damaged, the horn is damaged, and the fuse and other related accessories need to be replaced. Although the inside of the horn is airtight, if there is fog in the empty room inside or there is steam in the air during car washing, it is easy to know that the steam will cause the contacts to get damp and not work properly. Chery QQ horn does not sound treatment method:

If the headlight light is working and the horn is sounding, the battery is low. Follow the above method to inspect the battery and its connecting cables. In the case of insufficient battery, the car can drive normally, and when you need to honk the horn, you only need to increase the throttle appropriately.

2.If the headlamp brightness is normal, press the horn button system to check the relay for clicks. If yes, it may be that the horn is damaged or the horn is grounded faulty.

The horn assembly should be replaced or the ground fault should be eliminated. The horn relay is usually located on the lower left side of the steering wheel. For the location of the horn relay for different models, please refer to the car instruction manual and the fuse and relay identification plate on the vehicle.

Lazhiba is usually located under and behind the radiator (tank). If the horn is poorly grounded, the horn can be removed and reinstalled. If the horn is damaged, a new horn needs to be replaced.
