Why doesn t the horn go off, when the horn goes off, what is the reason?

The troubleshooting method of computer silence is as follows: (1) First, check whether there is a "small speaker" on the right side of the taskbar. If there is, the sound card is normal, and the fault may be caused by the system sound being too quiet, or muted, or the speaker is faulty.

You can continue to check if there is a sound output through the headphones, if there is, it is a fault of the speaker. (2) If there is no "Little Speaker" on the right side of the taskbar, then click the "Control Panel Sound and Audio Devices" command to open the "Sound and Audio Device Properties" dialog box, click the "Sound" tab in this dialog box, then click one of the program events in the "Program Events" bar (such as the program error), select a sound type, and then see if the "Preview" button on the right is black. If it is black, the sound card is normal, and the fault may be due to the system volume being too low, or mute, or the speaker is malfunctioning.

3) If the Preview button in the Sound tab is grayed out, click the Control Panel System Properties Hardware Device Manager command to see if there is a yellow color in the Device Manager window. ". (4) If there is a yellow "?

See if the option is a sound card device option (there are usually keywords such as "audio" or "sound" in the sound card device option). If it is an option for a sound card device, it means that the sound card driver is not installed, reinstall the sound card driver, and the problem of no sound can be solved. (5) If there is a yellow "?

6) If there is a yellow "! It may be caused by a mismatch in the driver of the sound card, or an aging sound card. Then remove the band "!

option, just reinstall the sound card driver. (7) If there is no sound card option in the Device Manager window, and the sound card is an integrated sound card, restart the computer and enter the BIOS program. Then check if the Peripherals option in the BIOS is set to "Disabled", and if so, change it to "Enable".

If I set this setting "enable", it may be that the sound card circuit of the motherboard is damaged, and the sound card circuit can be repaired. (8) If the sound card is not an integrated sound card, then open the case and check whether the sound card is installed. If it is not installed, after re-installation, boot the test; If the sound card has been installed, then remove the sound card, then clean the dust on the motherboard sound card slot and the sound card (especially check whether the gold finger has mildew spots, etc.), clean it, and then reinstall it, and the general fault can be eliminated.

9) If the sound card is still abnormal, there is a problem with the sound card, use the replacement method to check whether the sound card is damaged or incompatible with the motherboard. If the sound card is damaged or incompatible with the motherboard, replace the sound card. (10) Sound card driver**.

af&by=name&site=all It is recommended to install Driver Wizard 2008, after installation, use its automatic update driver function, it will automatically install and install the latest version of Driver Wizard. After running the software, it can automatically identify the hardware and automatically install the driver and update the driver,(You only need to wait for the automatic installation of the driver,) the address of the official website of the driver wizard。

Use the elimination method one by one: 1. Check whether the sound card, cable, and speaker and other devices are connected normally 2. Reinstall the driver of this device to solve the problem; 3. When there is sound but no speaker, open the control panel, sound and ** device, volume, and check in front of "put the volume icon into the taskbar"; 4. No sound and no speaker, open the control panel, add and remove programs, add and remove Windows components, put a check mark in front of "Accessories and Tools", click "Next", and then, shut down and restart, the system prompts to install new hardware, and install according to the prompts; 5. Uninstall the sound card driver and reinstall or upgrade it 6. When the sound card driver is installed, the prompt "AC chip cannot be found" appears, it may be that the computer is poisoned, or the sound card driver is deleted in violation of the operation, and the internal software conflicts. The solution is to reinstall the system and drivers.

7. After shutting down, wait for a period of time to restart the device"

Hello, the Mazda 6 horn sometimes doesn't work. It may be that the paddles inside the steering wheel are too dirty, or the position is not good, and the contact is not good, which causes it to be difficult to use. Or the return ring of the airbag is faulty, there will be an occasional bad phenomenon, I hope to help you, I wish you a happy car!

Car questions, ask the car guru. 4S shop professional technician, 10 minutes to solve. 】

When the horn of the electric car rings, it doesn't sound, just because this screw is loose, and the master is in it!

Take it apart and take a look, the line is not in good contact, and it may be loose when touched.

Lao Xu repaired the tram circuit and the electric vehicle instrument is abnormal, and the horn does not sound when it sounds? The master solves it by dividing it by two!

1. It may be a problem of open circuit of the speaker power line, you can check the line to see if it is smooth, or cut off, if so, then connect the line.

2. It may be that the horn button is in poor contact. Poor contact can also cause a bad sound, so you can check it and fix the contact point.

3. It may be that the relay contact is ablated or the gap is too large, and the magnetic coil of the horn is broken.

4. It may be that the armature air gap of the horn is too large. If the armature air gap is too large and the horn does not sound, this situation can also be repaired, and it can be dealt with.

5. It may be that the horn is washed with water when washing the car without sounding, at this time you need to see if the horn has been damaged, if it is damaged, it needs to be replaced.

If the car horn does not sound, you should first distinguish whether it is a fault of the line or a problem with the horn itself. Line faults typically include horn relay contact ablation, horn plug terminals, poor contact of the horn switch at the steering wheel, etc. And the car horn does not sound, which is usually the reason for the horn itself.

Faults in the horn itself include contact ablation, poor sealing, susceptibility to moisture, and poor contact of solenoid terminals.

1. The seal is not tight. The inside of the water inlet horn is sealed, but if the sealing is not tight, the water vapor entering the car can easily cause the contacts to get damp and not work properly.

2. Poor contact of solenoid coil terminals. If the insulating paint on the enameled wire on the enameled wire at the end is not cleaned, or the rivet is not crimped firmly, it is easy to cause the horn to not sound. This kind of failure can only be replaced, not repaired.

3. Pressing the horn for a long time causes contact ablation. Pressing the horn for a long time is easy to cause the horn contact to be ablated and produce impedance, so that the current through the electromagnetic coil is weakened, and the armature cannot be attracted to drive the diaphragm to vibrate normally, resulting in the horn not ringing. However, when the horn is constantly pressed, the instantaneous strong current will still work normally through the impedance, so it will be good and bad.

Therefore, when using the speaker at ordinary times, we should pay attention to the following points: 1. The cause of the failure of the speaker should be determined first, and do not blindly replace it, resulting in unnecessary waste; 2. When washing the car, prevent the horn from drenching water, and dry it with an air gun as soon as possible if the water is in. 3. Do not press the horn for a long time to prevent premature ablation of the contacts.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! The reason is that the horn is damaged.

1.The horn does not sound after it is damaged, and there is electricity after unplugging the horn. 2.

Unplug the horn and measure it with a test lamp, and replace the horn if there is electricity. The horn is indirectly controlled by the horn switch, as long as there is no problem with the wire and the measuring plug has electricity, it is the horn problem.

What is the reason why the horn does not sound.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! The reason is that the horn is damaged. 1.

The horn does not sound after it is damaged, and there is electricity after unplugging the horn. 2.Unplug the horn and measure it with a test lamp, and replace the horn if there is electricity.

The horn is indirectly controlled by the horn switch, as long as there is no problem with the wire and the measuring plug has electricity, it is the horn problem.

One of your horns doesn't make a sound.

If the horn in the car doesn't sound, it's a CD player problem.

Here's why:

1. The battery storage is insufficient; 2. The horn relay or button is damaged; 3. The horn is damaged. In the process of ordinary car use, if you feel that the sound is not crisp, low and weak, it is a poor contact point; If the horn sometimes sounds and sometimes does not sound, it is because the contact inside the switch is not in good contact; The horn does not sound at all, you need to check the fuse to see if it is blowing, and use a multimeter to measure whether there is electricity here when the horn switch is pressed.

Hello, there are several reasons why the car horn does not 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 coil terminals: some of the internal electromagnetic coil enameled wire terminal joints of the horn are connected by aluminum metal rivet crimping, and the non-reliable welding is connected back to the base, 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 a virtual connection fault, resulting in poor working of the horn.

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.

Fault self-test if the horn does not sound:

1. If the sound of the horn is dull, it is likely that the horn itself is faulty, and as long as you knock on the horn, most of them can be improved. Other reasons are poor contact of the joints, especially the wires around the steering wheel, which are prone to wear and tear due to frequent use.

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

3. Turn the steering wheel left and right, if there is a large "hissing" friction sound, you can spray some grease into the relevant contact parts.

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

5. The working condition of the horn is related to the working condition of the battery at low speed of the car, if the energy of the battery is reduced, the sound of the horn is also reduced, and the battery storage capacity is normal.

6. If the horn does not sound at all, first check the fuse leakage to see if it is fused, then unplug the horn plug, and use a multimeter to measure whether there is electricity here when pressing the horn switch. If there is no electricity, the speaker harness and horn relay should be checked; If there is electricity, it is a problem with the horn itself, at this time, you can also try to adjust the adjusting nut on the horn to see if it can make a sound, if it still does not sound, you need to replace the horn.

7. If the seal is not tight, it is easy to get damp, although the inside of the horn is sealed, but if the seal is not tight, go to the car wash, it is easy to enter the fog or there is water vapor in the air in the internal space, and the water vapor can easily cause the contacts to be damp and not work normally.
