What s going on with the car interior and central control squeak?

The abnormal sound of the center console of the car may be due to the aging of the internal parts of the car and the loosening of the internal parts of the car, which may lead to the abnormal sound of the center console. If the sound of the abnormal noise of the center console is not very loud, there is no need to repair, the abnormal noise of the center console is mostly caused by the aging of internal parts, especially for a relatively long age of vehicles, for a long time bumpy, the internal parts of the body will produce a slight vibration or torsion, in this case, the internal parts of the car will produce abnormal noise. If the car is in the process of driving, the abnormal noise is relatively loud, you can ask professional maintenance personnel, remove the center console, check one by one, and fix the parts that are easy to loosen or friction between each other, and if there is deformation or damage, it is recommended to replace it if necessary.

If you really can't find the reason for the abnormal noise in the central control of the car, it may be that the internal gap of the center console is relatively large, you can find some sponges and other things to pad in it to eliminate the gaps, and there is a situation that there will be abnormal noises in the cold car state in winter, and it will be good to wait for the car to drive for a while, this situation is a normal phenomenon and can be ignored. Cause of failure 1The fan belt is too tight and too loose.

2.The generator bearing is damaged and stuck by the main or loose and lack of oil, and the bearing steel ball guard falls off. 3.

The generator rotor collides with the stator, i.e. "sweeps". 4.The brushes are worn too much, or the contact angle between the brushes and the collector ring is skewed, and the brushes are tilted and oscillated in the brush holder.

5.When the generator** parts are not in place, the body is tilted or the generator armature shaft is bent. 6.

The generator drive pulley and shaft are loose, so that the drive pulley collides with the heat dissipation fan. Fault diagnosis 1Check the tightness of the fan belt.

2.Monitor whether the generator drive pulley and generator installation are loose. 3.

Touch the generator shell and bearing with your hands, if there is a hot feeling, it means that the stator and the rotor are in contact or the bearing is damaged. 4.Listen to the bearing part of the engine, if there is an irregular crisp sound, it means that the bearing is short of oil or the ball has been damaged.

5.Remove the brushes, observe and test their integrity, if the wear is too large, it will lead to poor contact failure. 6.

Check the coordination and lubrication of the internal parts of the generator, and check whether the diode and magnetic field coil are short-circuited or open-circuited.

The main reason for the car's interior and central control squeak is that one of its overall control centers is affected, and you can open the hood to see if it's damp inside, and then try to dehumidify it, so it should be fine.

The reason why the center console rings:

1) If the plastic mold is deviated or installed with displacement, the bump causes the sound of mutual friction and squeezing loosening, find the position of the sound to confirm the friction point, and put on the rubber to block it, which has a good cushioning effect, 2) If not, find the inner tube of the car to do, if it is loose, first tighten the buffer of the rubber.

The solution to the abnormal noise of the center console:

1) Pay attention to listening and observing in the slow line, pay attention to determine the location of the abnormal noise, and see if you have inadvertently put in any foreign objects, such as the small wire in the toolbox by the baby, whether there is a foreign object in the gap of the central controller, whether there are debris around, such as what baffle or septum, if it is still the sound of the waves after cleaning, most of the parts of the central controller are in the process of frequent use, individual parts are loose, or the installation is not in place during the modification, and so on, 2) There is no tightening of the screws when modifying the audio, The gap between the baffles can be plugged with silicone or whether the plastic pipes connected to the air outlet adjustment device are broken due to cold and heat changes, as well as the air outlet pipes connected by the two air outlets on both sides of the CD machine, which are located on both sides of the CD machine, are also the biggest suspicion of abnormal noise sources. (3) From beginning to end, I screwed the place that should be tightened once, and then cleaned the central controller, I felt that the abnormal sound was the seam at the air outlet of the air conditioner, and there were 2 clips up and down the air outlet, which can be removed by gently prying with a screwdriver at the bottle mouth.

1. Although the abnormal noise of the center console cannot be said to be a normal phenomenon, it is a relatively common phenomenon that exists in many models.

2. This abnormal sound generally occurs in the instrument panel or the interior panel of the door and other parts with more plastic parts, especially when the vehicle is driving on the uneven road surface, due to the bumpy road surface, the body will produce a certain vibration or slight torsion, so that these plastic parts inside the body will produce resonance abnormal sound.

3. Or squeeze each other to cause friction noise, generally this kind of abnormal sound will change with the change of season and ambient temperature, although this kind of abnormal sound will not have any impact on the driving performance of the vehicle, but it does sound annoying.

4. If you want to eliminate this kind of abnormal noise, you need to disassemble and inspect the parts that make abnormal noises to see if there is poor assembly and whether there are loose parts that need to be retightened.

5. Or install shock-absorbing and anti-noise pads in the parts that are in contact with each other and the parts where there is a loose gap, so you can go to the repair shop to conduct on-site test inspection and treatment of the vehicle according to the above analysis.

Reasons for the abnormal noise of the center console of the car: 1. Although the abnormal noise of the center console is not a normal phenomenon, many cars will have some noises more or less, if the individual can accept it, do not need to pay attention to it, if the noise is loud and obsessive-compulsive disorder is unacceptable, it is recommended to check whether the parts of the center console are loose; 2. The abnormal sound of the center console generally occurs in the instrument panel or the interior panel of the door and other parts with more plastic parts, especially when the vehicle is driving on the uneven road, due to the bumpy road surface, the body will produce a certain vibration or slight torsion, so that these plastic parts inside the body will produce resonance noise, or squeeze each other to cause friction noise; 3. It can be checked by erasing the center console, and the parts that are easy to loosen need to be re-tightened, and the parts that are easy to rub against each other and have contact with each other can be checked to see if there are other sundries or parts damaged and deformed, and the parts can be replaced if necessary. If some gaps are caused by too large, rubber gaskets can be used to fill them.

Most of the abnormal noise of the car center console is the sound of the plastic mold deviation or installation displacement, and the sound of mutual friction and squeezing loosening caused by bumps, find the position of the abnormal sound to confirm the friction point, and put on the rubber to block it, which has a good cushioning effect.

Most of the abnormal noise of the center console of the car bump is the deviation of the plastic mold or the displacement of the installation, and the sound of the bump causing mutual friction and squeezing loosening, find the position of the sound to confirm the friction point, and put the rubber on the rubber to block it, which has a good cushioning effect. If not, find some inner tube of the car to do, if it is caused by looseness, first tighten it to make a rubber cushion.

The solution to the abnormal noise of the center console:

1. Listen and observe in the slow line, pay attention to determine the location of the abnormal sound, and see if you have inadvertently put in any foreign objects, such as the small wire in the toolbox by the baby, whether there are foreign objects in the gap of the central controller, whether there are debris around, such as what baffle or septum, if it is still the sound of the waves after cleaning, most of the parts of the central controller are loosened during frequent use, or the installation is not in place during modification, and so on.

2. There are no tightening screws when modifying the audio, the gap between the baffles can be plugged with silicone or whether the plastic pipes connected by the air outlet adjustment device are broken due to cold and hot changes, and the air outlet pipes connected by the two air outlets on both sides of the CD machine are also the biggest suspicion of abnormal noise sources.

(3) From beginning to end, I screwed the place that should be tightened once, and then cleaned the central controller, I felt that the abnormal sound was the seam at the air outlet of the air conditioner, and there were 2 clips up and down the air outlet, which can be removed by gently prying with a screwdriver at the bottle mouth.

When the clutch release bearing is damaged, the clutch plate cannot be completely disengaged, which eventually leads to an abnormal sound during acceleration.

On the issue of abnormal noise of automobiles, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. In the case of a turbocharged engine, there is a must be a difference between the sound and the sound of a naturally aspirated engine; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that they lack their own understanding of mechanical knowledge, so they can distinguish the abnormal noise of the car and avoid wasting time and energy.

Second, the identification method of car noise:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire cut-off to reduce the sound to meet the diagnostic needs. The auscultation site should be kept quiet to minimize human interference.

The solution to the abnormal noise in the central control of the car:

1. If the plastic mold is deviated or installed with displacement, the bump causes the sound of mutual friction and squeezing the late beam to loosen, find the position of the sound to confirm the friction point, and put on the rubber to block it, which has a good buffering effect;

2. If there is no good fruit, you can find some inner tube of the car to do, if it is loose, it is tightened first to make the rubber cushion;

3. Pay attention to listening and observing in the slow walk, pay attention to determine the location of the abnormal sound, and see if you have inadvertently put any foreign objects, such as the small wire placed by the baby in the tool code socks transport box, whether there are foreign objects in the gap of the central control, and whether there are debris around;

4. For example, what baffle or septum, if the sound is still the same after cleaning, most of the parts of the central controller are loose during frequent use, or the installation is not in place during modification, and so on.

What should I do if there is an abnormal noise in the central control of the car? What should I do if there is an abnormal noise in the central control of the car? The solution to the abnormal noise in the central control of the car:
