It is normal for a car to malfunction. What our drivers can do is to reduce the occurrence of car faults, to provide protection, and to be able to detect faults and discharge them in time. Here are some common faults that the small series has compiled for the riders about the sunroof of the car. Common sunroof failure A friend of Xiaobian asked me for help the day before yesterday, saying that his car was used for more than 2 years. He recently put the car downstairs (outdoor parking lot) for a period of time. The skylight was closed at the beginning and there was an abnormal noise, which coincided with Guangzhou on the same day. When the next one is bigger, it will enter the water. If it stops, it will not stop. He hurts in the car and washes it. When Xiaobian observed his skylight situation, he summarized several situations that may cause the sunroof to malfunction. 1. The sunroof sealing strip is aging and deformed. Natural rubber is known to be more prone to aging, especially in the sun and rain. The sun's ultraviolet rays and its high temperature make the skylight rubber age hard and chapped. Although the sunroof seal is commonly used in synthetic rubber, it is a heat-resistant, deformation-resistant, corrosion-resistant variety. However, it should be established in the case of normal maintenance. Generally, every 2 to 3 months, wipe the sunroof sealing strip with a wet sponge, then spray the rubber maintenance agent, and finally open the sunroof completely and then close it completely and repeatedly to make the protective agent cover the surface of the rubber layer. 2. Insufficient lubrication of the moving mechanism in the window The skylight actually has a long life. In the first two years or even two or three years of its initial use, there will be no leakage or abnormal noise. These conditions are usually caused by the owner's lack of maintenance of the sunroof or the method is wrong. My friend felt that the grease on the sliding track was dirty, and it was directly wiped off with a paper towel to apply a new layer of grease, which aggravated the damage of the sunroof. Usually, the sunroof should be started from lubrication. After a few years, the car will be less or less lubricated and will be dusty. At this time, it is necessary to clean the old grease and apply new low-speed grease. In addition to lubrication, this grease protects the surface of the machine and isolates air and moisture, ensuring that the parts are not susceptible to rust and aging. 3, the sliding track groove in the window has leaves, sundries Some car owners usually do not pay attention to the maintenance of the car sunroof, but also relatively "big head shrimp", the old forgot to close the sunroof, causing some leaves, dust, bird droppings and other debris may enter the sliding track in the skylight, causing the sliding track to be stuck, Wear, corrosion, and serious damage to the sunroof assembly. Generally speaking, there is grease on the sliding track, which is used to lubricate the skylight, but the grease exposed to the air has inadvertently “cleaning†effect, sticking to the road and flying (matching, picture, inquiry) The dust of the price, in this way, became a "sandpaper." If the dust is not cleaned up in time, when the sunroof is closed, the “sandpaper†will continue to grind the track and the skylight, and the loss will naturally accumulate over time. When the accumulation of dust and foreign matter reaches a certain level, the running resistance of the sunroof will increase, which will cause the sunroof to falsely start the anti-pinch function, which may cause the sunroof not to be completely closed. There is also a case where the sundries block the sunroof's sink. In addition to affecting normal drainage, it also corrodes the sunroof. The above is some of the finishing of the car's common faults for the car owners to hope that the riders can understand.
