How to solve the abnormal noise of the sunroof of the car? What should I do if the sunroof of a vehi

Now the car is basically a load-bearing body, the material used in the body is different from the material of the sunroof skeleton and glass, different materials will produce different amounts of deformation, when there is torsion and deformation in the body on the bumpy road, it is easy to have abnormal noise, and the internal parts of the sunroof are also more, and it is easy to loosen after long-term driving on uneven roads, so the abnormal sound of the sunroof is one of the more common problems.

For example, the abnormal noise of the Sunroof is caused by the friction between the sunroof glass rubber strip and the roof iron plate, which can be solved by spraying the surface wax at the external rubber strip position, or cleaning the rubber strip and adding some hand cream used by women.

In addition, there is a possibility that the sunroof interior trim between the loose noise, this situation needs to be solved by plugging the non-woven fabric, secondly, most of the sunroof fixing screws are loose, resulting in the vibration and collision of the two parts. This situation can only be solved by tightening the screws, sometimes it can be re-tightened from the side of the canopy, and sometimes it needs to be removed from the entire canopy.

Sunroof abnormal noise is generally not solved if simple treatment, and abnormal noise only appears on the bumpy road, it is recommended not to remove the canopy, the canopy installation of the vehicle is mostly made of plastic buckles, disassembly and assembly is prone to buckle breakage or installation is not tight, sometimes the more repaired the louder.

In fact, for a car, the overall rigidity of the body, the tightness of the sunroof slide, the weather and the use of the environment and other factors will actually cause the sunroof abnormal noise, this not only appears in the panoramic sunroof, but the ordinary sunroof will actually be, but the probability of the occurrence of the panoramic sunroof will be higher.

Why is that? Let's first talk about the problem of body rigidity, in fact, in the design process of the car, we must think of the problem of the overall body rigidity, if the rigidity is insufficient, it will occur in cornering, bumpy road and so on, slight rigid distortion occurs. If this is done for a long time, the body may be slightly deformed, and the windows will not fit properly.

However, now manufacturers have taken this into account when building cars, and will add stiffeners to the roof part to maximize the rigidity of the entire roof to become stronger, so as to suppress the rigid deformation of the body in corners and bumpy roads.

In addition, in fact, because the sunroof may be opened and closed frequently, which causes the loss of slide grease, and with the change of level, the performance of the grease decreases, which will cause abnormal noise at the junction of the glass and the slide rail on bumpy roads.

If you want to remove the abnormal noise, the first thing you can do is to remove the electric sunroof, and thoroughly clean the mechanical structure of the glass plate and the slide rail, especially to remove the grease and dirt remaining on the mechanical structure, which may be the main cause of abnormal noise.

In addition, if the body is really deformed and the glass panoramic sunroof is abnormal, it may be a structural damage, and the general vehicle will not have this problem, we can imagine that if you make a big hole in the top of the plastic glasses case, then it becomes very easy to twist it.

The solution to the abnormal noise of the automobile sunroof is: 1. Open the sunroof to the end and spray the sealing strip maintenance agent; 2. Tighten the sunroof screws; 3. Use a towel to remove the dust; 4. Add lubricating oil to the sunroof track. The components of a car sunroof are:

1. a sliding mechanism; 2. a driving mechanism; 3. a switch button; 4. Control system. The maintenance methods of automobile sunroof are: 1. Regularly check whether the state of the sunroof guide rail is normal; 2. Reduce the frequency of use of sunroofs; 3. The sunroof cannot be opened when the car is cold in winter; 4. Before the rainy season, check whether the drainage status of the skylight is normal.

Prepare the corresponding tools, a handful of cone changes, a small bottle of grease, and a few sheets of toilet paper. and press the sunroof switch button to open the sunroof.

After opening the sunroof, observe that there will be a lot of dust, wipe the dust from the groove under the sunroof front curtain with toilet paper, and press the sunroof front curtain with your hand, feel that it is very relaxed, there is no such tightness, if there is, you need to apply some grease in the groove.

Wipe the slide rails around the sunroof with toilet paper, due to long-term use, there will inevitably be some debris particles on the slide rail, and the sunroof will rub against these sundries when driving in the slide rail, and then produce abnormal noise, so be sure to keep the slide rail clean.

Open the grease and apply it to the left and right rails of the sunroof, and be careful to check the sunroof before making more noises, as this is where the friction is greatest.

Take out a word to change the cone, the grease on the left and right sides of the sunroof is evenly coated little by little, and the grease is accurately coated in the slide rail, do not paint outside, or there will be no effect, after painting, in the place where the sunroof is abnormal, apply it again to ensure that it is smooth and smooth. Finally, back in the car, close the door, open the sunroof switch, listen carefully, then you should not hear the sound of the abnormal noise, repeatedly open and close the sunroof, the purpose of this is to make the grease fully distributed in each place of the slide rail, to ensure the combination with the sunroof, in this way, the sunroof in the process of driving, there is no friction, there is no abnormal noise!

You can be responsible for telling the landlord to go outside to modify a fur roof, and when you change it, tell the store people about the middle of the skylight and the rear beam, and ask them to deal with it by the way. Otherwise, what tampons and the like can solve the problem for a day at most, and it will ring again at the beginning of the next day. I was crammed with skylights, and in the end, I was fine after thousands of kilometers of flipped roofs.

Go to the after-sales service center to have a look, or find a general repair shop to repair it to see if it needs to be repaired.

1. The sunroof rubber strip or sealing rubber ring is aging.

The sunroof sealing strip is in the rain or sun environment for a long time, which is easy to age, and the rubber maintenance agent can temporarily restore the performance of the rubber strip. Open the sunroof all the way to the bottom and spray the sealant with the adhesive strip. Of course, the more direct way is to replace the sunroof strip;

2. The sunroof screw is loose.

Loose screws will cause abnormal noises in the ceiling and skylights, and even the hidden danger of sunroofs falling off. The solution is very simple, find the sunroof screws and tighten them;

3. There are dust particles in the sunroof slide.

When the sunroof is opened back and forth, the gap between the slide rails will inevitably accumulate a layer of ash, and when the dust accumulates to a certain extent, friction will occur when the sunroof is opened and closed, resulting in abnormal noise. You can use a towel to remove dust, and it is important to maintain it regularly.

Car sunroof maintenance recommendations.

1. In the process of washing the car, avoid using a high-pressure water gun to directly align the water column with the sealing ring. In this way, it is not only easy to deform the sealing ring under the pressure of the high-pressure water column and cause water to enter the car, but also damage the sealing ring to a great extent;

2. On extremely bumpy roads, it is best not to completely open the sunroof, otherwise it may cause deformation of related components or even damage to the motor due to too much vibration between the sunroof and the slide rail. In addition, it is strictly forbidden to open the sunroof when it rains or when the vehicle is being washed;

3. The biggest concern about using the skylight is rain leakage and water leakage, and the correct use and maintenance of the skylight can effectively avoid water leakage. Before entering the rainy season, in addition to cleaning the sand and dust in the gaps of the slide rails and sealing strips, a small amount of plastic protective agent or talcum powder should be sprayed on the sealing strips and other parts.

The abnormal noise of the sunroof during driving can be dealt with in the following ways, check the sunroof slide, and add a little lubricating oil if necessary. Check the sunroof fixation. If there is noise, it may be loose, causing abnormal noise.

Skyroof seals are exposed to rain or sunlight for a long time and are prone to aging. Rubber conditioners can temporarily restore the properties of the strip. The solution is to open the sunroof all the way down and spray rubber curing agent on the sealing strip.

It is also necessary to pay attention to the maintenance of the vehicle. If the above methods cannot solve the noise problem, you can try to adjust the sunroof screws to eliminate abnormal noise.

The sunroof should be cleaned after 2-3 months of use, mainly to clean the dust and particles in the cracks of the sunroof, because if it is cleaned, it will damage the parts of the sunroof. When cleaning, first remove the dust from the sealing strip with a rag and then add butter to lubricate. If the car is parked for a long time and is not used, it should be cleaned regularly, such as cleaning the sunroof parts such as the sealing ring with fine talcum powder, which can effectively extend the service life of the parts.

Skyroof seals are exposed to rain or sunlight for a long time and are prone to aging. Rubber conditioners can temporarily restore the properties of the strip. Open the sunroof to the bottom and spray the seal with maintenance agent.

Of course, the more straightforward way is to replace the sunroof strips;

Loose screws can cause abnormal sounds in ceilings and skylights, and even have the hidden danger of skylights falling off. The solution is very simple, find the sunroof screws and tighten them; As the skylight comes and goes, it is inevitable that a layer of dust will accumulate in the rail gaps. When dust accumulates to a certain extent, the sunroof switch will cause friction and produce abnormal noise.

Dust can be removed with a towel, and regular maintenance is important. During the car washing process, avoid using a high-pressure water gun to align the water column with the sealing ring. In this way, it is not only easy to deform the sealing ring under the pressure of the high-pressure water column, but also damage the sealing ring to a large extent; On extremely rough roads, it is best not to open the sunroof completely, otherwise the vibration between the sunroof and the slide rail may cause deformation of the relevant parts or even damage the motor.

In addition, it is strictly forbidden to open the sunroof when it rains or when the vehicle is being washed;

The biggest problem with using a sunroof is rain and water leakage. Proper use and maintenance of sunroofs can effectively avoid water leakage. Before entering the rainy season, in addition to cleaning the dust between the slide rail and the sealing strip, a small amount of plastic protective agent or talcum powder should be sprayed on the sealing strip and other parts.

Why is it wrong to lubricate the sunroof? It's useful to say it's useless. However, lubricating oil and grease are easy to stick to dust and absorb dust, which can easily cause excessive wear and tear on the track, which greatly reduces the service life of the sunroof.

Open the sunroof, wipe the perimeter of the rails clean, and then clean it again with a special sunroof rail cleaner. After cleaning, dry in the sun, spray on the tracks and guide wheels, and open and close the sunroof several times. The special lubricant is non-oily and non-sticky, which can effectively and permanently reduce the wear of the sunroof track.

Do you want to see if this sound is coming from that location? Like that kind of lubricating oil, in fact, it is also possible to use ordinary lubricating oil directly, or you can apply a little petroleum jelly to the rubber strip.

The impact may be due to your poor contact or something, in which case you need to turn off the vehicle and relight it before restarting the sunroof.

If it doesn't sound badly, you can ignore it, and if it sounds very strong, you can go to a professional car repair shop to repair it.

Under normal circumstances, there are three situations in which the abnormal noise of the automobile sunroof is caused by the failure bend: first, the lubrication of the automobile sunroof slide rail is insufficient; the second is the dust accumulation on the skylight track; Third, the sunroof screws of the car are loose. Only the slides of the sunroof move during the opening of the sunroof.

If there is a sound, it may be that some parts are not well lubricated. Try applying some grease. It is also possible that the sunroof has been open for a long time, and a lot of dust has accumulated on the slide rails, which should make the sound disappear after wiping.

It may also be that the sunroof has been used for a long time, and some parts or screws are loose, and the sound should disappear after tightening the screws. The sunroof glass is connected to the body by a sunroof bracket. Visually, the sunroof bracket is relatively thin, and the cost control is too strict.

Over time, the displacement caused by the weight of the glass and the fatigue of the metal can easily cause shaking, friction and abnormal noise. The thickness of the corner pads under the two connecting rod shafts of the sunroof bracket is 8 mm, and the thickness of the corner pads at the tail is 4 mm, which is just right. In this method, the sunroof glass is changed from a half-hung original state to a compacted corner pad at three points on the left and right to achieve a soft connection.

If the sunroof is caused by the loosening of the sunroof fixtures, the aging of the sunroof parts, the presence of dust particles in the sunroof slide, etc., it is recommended to fix and tighten the sunroof screws, replace the aging parts, clean the sunroof slide and add lubricating oil. If it cannot be solved, it is recommended to go to the 4S shop for inspection and repair as soon as possible.

Car sunroof function:

1. It can be cooled down quickly.

If you happen to be parked under the sun when you park, the temperature inside the car is likely to reach more than 60 in the summer. The first reaction of many car owners when they get into the car is to turn on the air conditioner. In fact, the windows and sunroof should be opened first, and the sweltering air can be pumped out immediately during the driving process to cool down.

2. It can eliminate fog.

In the season when the temperature difference is large, if the side windows of the car are closed while driving, then the front windshield is prone to fogging. At this time, the owner only needs to open the sunroof for a few seconds to quickly remove the fog in front of him.

3. It can quickly change fresh air.

The sliding mechanism of the sunroof is a track type, and the general owner will have a lot of dust and sand particles in the contact surface and gaps of the slide rail after a period of use (3 6 months), and if it is not cleaned regularly, the "squeak" sound will naturally exist.

Under normal circumstances, there are three situations that cause abnormal noise in the automobile sunroof: first, the automobile sunroof slide is not lubricated enough; the second is the accumulation of dust on the skylight track; The third is the loosening of the screws of the car sunroof.

During the opening of the sunroof, only the sunroof slide is moving, if there is a sound, it may be that some parts are not well lubricated, you can try to apply some grease; It is also possible that the sunroof has been left open for a long time, which has accumulated a lot of dust on the slide rail, and the sound should disappear after wiping it off; It may also be that the sunroof has been used for a long time, and some parts or screws are a little loose, and the sound should disappear after tightening the screws.

Usually, car owners can use cotton cloth and gauze to wipe the track of the slide rail, and after wiping it clean, apply a small amount of butter to the slide track. However, car owners need to pay attention to the fact that the sunroof system also includes many rubber and plastic parts, and these parts cannot be in contact with oil or sticky substances, otherwise they will corrode.

When cleaning rubber and plastic parts, you only need to wipe it with a clean cotton cloth, and you can apply a little talcum powder on the surface to protect it after wiping it clean. The sunroof should be used frequently to avoid abnormal noises.
