The horn is not ringing, the horn is not broken, how to repair the car horn is not ringing?

If there is no sound from the speaker, please check it by following the steps.

1. Check whether the sound card, cable, speaker and other devices are connected normally. If you have a virus, you should run antivirus software for full antivirus.

2. Open the control panel--- Add new hardware--- Next, after the search is completed, click "No, I haven't added this hardware", click Next. In the dialog box that appears, check Click Done, shut down the computer, restart to add new hardware. Note that this refers to shutting down and then starting, not restarting.

In general, the problem can be resolved after rebooting.

3. Right-click "My Computer" --Properties ---Hardware--Device Manager" to open.

If so, uninstall it, then put it into the CD drive and reinstall the drivers for this device.

Then you have to find your sound card, including the integrated sound card, the model must be accurate, after confirming that the sound card is found, then put it into the system drive disk, and install the sound card driver.

--- the volume of the device, put a check mark before "put the volume icon in the taskbar", and put it in the taskbar after restarting.

There's a little horn again.

6. When there is no sound and no speaker, open the control panel ---Add and delete programs--- Add and delete.

windows component, put in.

New hardware, just follow the prompts to install it.

7. If you can't solve the problem, you have to reinstall the system and drivers, and everything is asked.

The problem will be solved, but only if the hardware is intact and the software is not conflicting.

8. When the sound card driver is installed, the "AC chip cannot be found" prompt appears, it may be that the computer is poisoned, or the sound card is plug and play loose, resulting in poor contact, and it may be that the sound is deleted by mistake due to illegal operation.

card drivers, or internal software conflicts. This has to be done step by step for different reasons.

Settle. 9. You can gently pat the shell of the computer body, and the laptop can be on the cover.

When the force is slightly greater than usual, so that some loose parts are restored, and wait for a period of time after shutting down.

Turn it back on again, and sometimes the sound problem will be restored.

The main reasons for the horn not sounding or hoarse sound are insufficient battery storage, damage to the horn relay and buttons, damage to the horn, etc.

1. Check the power supply system. Turn on the headlight switch, the headlamp is not bright 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. When the battery is insufficient, the car can drive normally, and when you need to honk the horn, you only need to increase the accelerator appropriately.

2. If the brightness of the headlamp is normal, press the horn button to check whether the relay has a click, click, and rattle sound, if there is, it may be that the horn is damaged or the horn is faulty, and 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 and relay identification plate on the car for the position of the horn relay of different models, and the horn is usually located behind the radiator (water tank). If the horn is bad, the horn can be removed and reinstalled; If the horn is damaged, you will need to replace it with a new one, such as this new 6-inch Infalis car horn.

3. Press the horn button for testing, if the relay does not sound, it may be that the horn relay or horn button is damaged. If the horn relay is damaged, the relay should be replaced; If the horn button is damaged, the horn button located on the steering wheel can be removed and the wire can be shorted for emergency.

Maintenance. (1) Always keep the appearance of the speaker clean, and the wiring should be firm.

2) Always check and tighten the fixing screws of the horn and bracket to ensure that they are reliable.

3) The fixing method of the horn has a great influence on its pronunciation. In order to make the sound of the horn normal, the horn can not be rigidly installed, so it is fixed on the buffer bracket, that is, a sheet spring or rubber pad should be installed between the horn and the fixed bracket.

4) Check the generator output voltage frequently. If the voltage is too high, the horn contacts will be burned out, and if the voltage is too low (lower than the rated voltage of the horn), the horn will make an abnormal sound.

5) When washing the car, do not rinse the horn directly with water, so as not to enter the horn and make the horn not sound.

6) When overhauling the horn, you should pay attention to the position of each metal pad and insulating pad, and do not install it wrongly.

7) The continuous pronunciation of the horn should not exceed 10s to avoid damaging the horn.

8) Do not put all kinds of foreign objects into the horn, so as not to cause abnormal sound.

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.

First of all, confirm whether the plug of the horn has power supply, if not, check whether the fuse is damaged, if it is not damaged, then check that the relay is not fine, if the above is fine, then pay attention to the damage of the airbag hairspring.

Summary. Hello, dear. The reasons and solutions for the car horn not to break but not sound are as follows:

1. If the woofer does not sound at the same time, it is likely that the fuse is burning, and the fuse can be replaced. 2. Connect the positive and negative electricity directly to the horn, if the horn does not sound, it proves that the horn is broken, and it can be replaced. 3. The relay can also be short-circuited, if the horn sounds, it proves that the relay is broken, and the relay is replaced directly.

4. Directly short-circuit the control switch with wire, if the horn sounds, it proves that there is a problem with the contact of the control switch, and the contact of the control switch is replaced.

The car horn is not broken, but it is the matter that it does not sound.

Hello, dear. The reasons and solutions for the car horn is not broken but does not sound are as follows: 1. If the woofer does not sound at the same time, it is likely that the fuse is burned, and the fuse can be replaced.

2. Connect the source of positive and negative direct sales to the horn, if the horn does not sound, it proves that the horn is broken, and it can be replaced. 3. You can also short-circuit the relay electrical relay, if the horn rings, it proves that the relay is broken, and the relay is replaced directly. 4. Directly short-circuit the control switch with the wire, if the horn rings, it proves that there is a problem with the contact of the control switch, and the contact of the control switch is replaced in the neutral state.

There are three reasons why the car horn does not sound: 1. Poor sealing: If the sealing is not tight, the water vapor entering the car washing can easily cause the contacts to be damp and not work normally.

2. Poor contact of solenoid terminals: if the insulating paint on the enameled wire of the loose end end is not cleaned, or the rivet is not crimped firmly, it is easy to cause false connection, resulting in the horn not ringing. This kind of failure can only be replaced by a horn.

3. Contact ablation caused by pressing the horn for a long time: pressing the horn for a long time is easy to cause the contact ablation of the horn and produce a chaotic impedance, which weakens the current through the electromagnetic coil and cannot attract the armature to drive the diaphragm to vibrate normally, resulting in the horn not ringing.

Car horns are an important part of the vehicle and play an important role in alerting other vehicles and pedestrians. If you find that the car horn is not broken but does not sound, you must find out the cause and repair it as soon as possible.

The first reason could be a power failure. Check whether there is a short circuit or open circuit in the circuit line of the vehicle, and check whether the horn power cord is in good contact. You can use a voltmeter to test whether the circuit is working properly to ensure that the power supply can be properly applied to the horn.

The second reason may be a faulty horn switch. Check whether the horn switch is not working properly because the joystick is broken or the orange core block of the electronic mold is damaged. If the switch is not working properly, the part needs to be replaced.

The third reason could be the malfunction of the horn itself. There may be a fault with the motor or sensor inside the horn that can be repaired or replaced by trouser rolling.

In conclusion, if the car horn is found not sounding when alerting others, the driver should find out the cause of the problem as soon as possible and repair it. This ensures that the vehicle can alert other vehicles and pedestrians in time for an emergency, thus avoiding accidents.

Car horn is a very important safety device when we drive, it can alert other vehicles and pedestrians and remind ourselves of our presence while driving. However, sometimes we find that the horn does not sound, so what should we do? The following will analyze the reasons why the car horn does not sound and the corresponding solutions.

1. Horn line failure.

When the horn of the car does not sound, the first time should check whether the horn line is faulty. Inspection method: Find the snail shell (the horn solenoid valve of the car, generally rectangular or square) at the engine of the vehicle, and touch the two holes on the shell respectively.

If it is found that one hole vibrates strongly (in a state of vibration) and the other does not move, it may be caused by the fault of the horn line.

Solution: Find the fault point, and then use a multi-purpose trouser meter or electrician pen to test it on the spot according to the horn circuit diagram. Find the place where the horn is waterlogged or rusty, weld or replace it, and then use the horn again.

Second, the internal fault of the horn.

Internal faults in the horn are also a common cause of the horn not sounding. When the vehicle is moving, the horn has a sound similar to intermittent, or the sound is extremely weak, it can basically be confirmed that the horn is faulty.

Solution: Disassemble the horn, wipe the horn rod, clean the horn debris, check the resonance chamber for impurities, etc. If the problem is not solved, it may be that the solenoid valve coil is broken and needs to be disassembled and tested, and if the old stool cannot be repaired, it needs to be replaced with a new horn.

3. The battery voltage of the car is low.

When the battery voltage is lower than the installation requirement, the car horn will not be able to make a normal sound. This often happens with old cars that have been in use for a while.

Solution: First of all, you need to detect the battery voltage of the vehicle. If it is lower than 11V, you need to use a car charger to charge the battery; If the voltage is between 11 and 12V, the battery needs to be replaced, and the performance of the battery will decrease after aging, so it needs to be replaced in time to avoid hidden dangers for future use.

Conclusion The car horn does not sound can be said to be a great trouble for our drivers, however, we should always be vigilant about this matter. When the car horn does not sound, you can first check whether the horn line is faulty, and then further check the internal fault of the car horn or the low voltage of the car battery, so as to find the accurate cause of the fault and ensure the driving safety of yourself and others. I believe that as long as we carefully maintain the car during driving, the corresponding problems will not be too much trouble.
