Why does the Venucia car horn not sound when it is cold?

This is to check whether the line plug of the lower horn is not in poor contact. Or there is a problem with the inside of the horn and the horn needs to be replaced. You have to ask the repairman to check it, this is a good thing to find.

Hello, the horn does not sound and needs to be checked, the general probability of damage to the horn is relatively large, press the horn to measure whether the horn plug has electricity, if there is electricity, the horn is damaged, and the switch and line can be checked if there is no power.

In this case, it generally has nothing to do with the hot or cold weather. It should be caused by a fault in the line, so it is recommended to check it.

The original line is too long, the power supply to the horn and then to the steering wheel iron, the current will be much smaller, after adding the relay horn directly iron, the current is large, the horn will sound.

Hello, according to your description of the situation analysis, you can press the horn button at the same time, check whether the relay is engaged, generally the relay problem, the phenomenon caused, I am happy to answer for you!

Hello, this is generally because of the problem of the car's wiring, you can check it or the fault of the horn itself.

Hello, it should be caused by poor contact inside the horn or horn wiring harness, it is recommended to go to the repair station to check it.

Check if there is a problem with the wiring or poor contact with the horn, it is best to go to the auto repair shop and 4S shop to check to see if there is a problem.

Hello, your situation should be caused by the wiring of the car. There was a short circuit, it is recommended to check it.

Hello, this phenomenon should be a problem with the connecting wire. If it is a horn that is installed later. Also check for relays.

Hello, your situation may be caused by poor contact of the horn line, it is recommended to check the line.

If this is the case for you, focus on checking the connection of the line, it may be that the line connection is poor, and check the battery voltage.

Hello, the problem you said should be caused by poor contact of the horn line, you can go to the 4S store to check it.

There are many cases, and there may be problems with the speaker itself or the possibility of the line, so go and check it directly.

Hello! It is recommended to go to the local 4S store to test whether it is a horn problem, or replace it with a new one

My southeast dx7, put it cold all night, it doesn't sound at all in the morning, wait for an hour or two, it rings again, it rings at any time in summer, what the hell is going on.

When it is cold, the horn does not sound for the following reasons:

1. Poor contact of the connecting wireIf the cold car honks the horn and turns the steering wheel at the same time, if it rings intermittently, it means that the connecting line at the direction column is loose or badly discharged.

2. Frozen

Use a heater to blow the horn, if the car rings cold, it means that the horn is frozen on the day;

3. Steering wheel problems

There is a spring bolster at the steering wheel, there is butter, it may be that the butter sticks to the cold weather and does not rebound, and the hot car is good (not suitable for all models);

4. Fuse box joint problem

The section from the horn to the fuse box has poor joint contact, and the cold car does not contact due to thermal expansion and cold contraction, and the connector is re-plugged and connected.

5. The seal is not tight, and it is easy to get wet

Although the inside of the horn is sealed, if the seal is not tight, if the car is not tightly sealed, it enters the fog or there is water vapor in the air in the internal space, the water vapor can easily cause the contacts to be damp and not work properly.

It should be that the line contact is poor, or the contact contact inside the relay is not good, it is recommended to pull it out and wipe it with sandpaper, and the line can only go to the maintenance plant, which is not a big problem! Don't worry, dear, the next time you cross the gear bar, you might as well try flashing high beams!

Whether it is a car wash or rain when the snail horn is flooded, the weather is cold and icy, the horn vibrating diaphragm is frozen, sometimes the ice melts and can sound but there is water blocking the vibrating diaphragm to make the sound small, remove it and pour out the water inside.

It was the cold weather that affected the line, and it had nothing to do with the horn itself.

Poor contact Check the line! It has nothing to do with hot or cold!

Maybe the ** line has to ask, ask the master to check it for you, and see how the fuse is.

The horn does not sound when the weather is cold, which basically belongs to the following reasons:

1. The line is loose or in poor contact. If the cold car honks the horn and turns the steering wheel at the same time, if it rings intermittently, it means that the connecting wire at the direction column is loose or in poor contact. First look at whether the horn fuse is blown if the fuse.

There is no problem, focus on checking whether the wiring of the horn is loose, or whether the contact of the horn button is poor, most of the cases are the problem of contact or wiring, and it can be solved after simple processing.

2. Failure caused by too low temperature. Use a heater to blow the horn, if the car rings cold, it means that the horn is frozen on the day; There is a spring bolster at the steering wheel, there is butter, it may be that the butter sticks to the cold weather and does not rebound, and the hot car is good (not suitable for all models);

3. The section from the horn to the fuse box has poor joint contact, due to thermal expansion and cold contraction.

The reason is that the cold car does not touch, and the connector is re-plugged and connected.

4. Caused by poor grounding of the steering cross shaft under the steering wheel, due to the poor conductivity of the cold cross shaft, the horn power supply can not form a grounding and a path, so the horn does not sound, and the horn is normal after the car is hot. In this case, you can find a one-meter-long copper conductor and short the steering shaft.

5. The seal is not tight, and it is easy to get wetAlthough 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.

Water vapor can easily cause the contacts to become damp and not work properly.

When it is cold, the horn does not sound for the following reasons:

1. Poor contact of the connecting wireThe cold car honks the horn and turns the steering wheel at the same time.

If it rings intermittently, it means that the connecting wire at the direction string is loose or badly discharged.

2. FrozenUse a heater to blow the horn, if the car rings cold, it means that the horn is frozen on the day;

3. Steering wheel problemsThere is a spring bolster at the steering wheel, there is butter, it may be that the butter sticks to the cold weather and does not rebound, and the hot car is good (not suitable for all models);

4. Fuse box joint problemThe section before the horn to the fuse box has poor joint contact, due to thermal expansion and cold contraction.

The reason is that the cold car does not touch, and the connector is re-plugged and connected.

5. The seal is not tight, and it is easy to get wetAlthough 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.

Water vapor can easily cause the contacts to become damp and not work properly.

Habitual application of automobiles, automobiles inevitably produce some problems. And every time it is winter, the problems that occur in the car increase significantly. In winter, many car buyers encounter the situation that the horn suddenly does not sound in winter, and these problems cannot be found in hot weather.

So why doesn't the horn go off when it's cold? Let's study the reason why the horn doesn't sound in winter.

It is very likely that the horn does not sound in winter.

1. Ultra-low temperature is too low to cause common faults. Use an electric heater to blow the horn, if the horn goes off when the car is cool, it means that the temperature is too cold to hide the horn.

2. The lower speaker line contact of the car steering wheel is a theme activity contact, with butter inside, the butter is getting thicker and thicker in the cold weather in winter, and the contact is sticky and can not be retractable.

3. There is poor contact between the horn and the middle of the fuse box. Because the temperature is low in winter, the heat rises and shrinks, resulting in the instability of the connector, and the horn does not sound.

4. If the horn is intermittent, it indicates that the electrode connection line at the junction of the steering column in azimuth is loose or in poor contact.

The way to repair the horn without sounding in cold weather.

In winter, you can choose to heat the car in situ for 5-10 minutes to try to melt the freezing of the car horn, and this method can also reduce the viscosity of the butter in the contact of the horn line under the steering wheel of the car. You can also use an electric heater to blow at the horn to melt the freezing. Check whether the horn route is a bad contact phenomenon, if there is a problem in the route, it is best to go to the technical professional maintenance organization to maintain, to avoid the secondary damage caused by the actual operation of the autonomous.

If you use the car regularly, it is inevitable that there will be some problems with the car. And every time it comes to winter, there will be a significant increase in car problems. In winter, many car owners will encounter the situation that the horn suddenly does not sound in winter, and there will be no such problem when the weather is hot.

So why doesn't the horn sound when it's cold? Let's take a look at the reasons why the horn doesn't sound in winter.

There may be some reasons why the horn does not sound in winter

1. The low temperature is too low to cause failure. Use a heater to blow the horn, if the horn goes off when the car is cold, it means that the weather is too cold to blow the horn.

2. The contact of the speaker line under the steering wheel is a movable contact, which contains butter, and the butter becomes viscous when it is cold in winter, and the contact is sticky and cannot be expanded.

3. There is poor contact between the horn and the fuse box. Due to the cold weather in winter, the thermal expansion and contraction lead to unstable joints, and the horn does not sound.

4. Press the horn and turn the steering wheel in the cold car, if the horn sound is intermittent, it means that the connecting wire at the connection of the direction column is loose or in poor contact.

The maintenance method of the horn does not sound in cold weather

In winter, you can use the method of heating the car in situ for 5-10 minutes to try to melt the ice of the car horn, and this method can also reduce the viscosity of the butter in the contacts of the horn line under the steering wheel. You can also use a heater to blow on the horn to melt the ice. Check whether the horn line is in poor contact, if there is a problem with the line, it is best to go to a professional maintenance organization for maintenance to prevent secondary damage caused by self-operation.
