The window is not going up and down smoothly and there is a lot of noise. What caused it? Let me tell you something.

The essence of a car is just a consumable. After several years of use, various thorny problems will appear. I can't handle the bigger fault myself, so I have to go to the 4S shop to repair it. Moreover, some small problems in the car are the most annoying to the owner, with many problems, troubles and high maintenance costs. For most car owners, these minor problems can be postponed as long as they do not affect their daily driving. But, these humble little problems? Over time, it will also lead to major failures.

For example, the lifting of the window, after a long time, will appear this small problem, the window is stuck, abnormal sound, lifting difficult. Although this problem will not affect daily driving. However, driving is still annoying, so how to deal with these problems?

The failure that the window is difficult to lift is probably due to the dust accumulation or aging deformation of the rubber guide groove on the window glass. Coupled with the constant corrosion caused by wind and rain, the resistance of the window glass will increase when it rises and falls, and the resistance on both sides of the glass is inconsistent, which will easily lead to the skew of the window when it rises and falls. When there are many dirty things in the guide groove on the window glass, you will hear the sound of "zi zi" when you lift the glass.

In this case, you can wipe the inside and outside of the window strip with a rag and detergent to keep the environment clean and tidy. However, it should be noted that the lower part of the window will be thicker, and there will be more dust and debris, which needs to be wiped repeatedly. In addition, I believe that most car owners have had the experience that their windows are jammed with small cards. After stopping, they came back to find that the windows on both sides of their car were "surrounded" by various small cards.

These small cards will easily fall into the door frame through the cracks in the window glass, and this small paper card will melt into a ball when it meets water. Thereby blocking the drain hole on the door frame, and it will also produce odor after a long time. It will also lead to short circuit of lifting motor due to untimely heat dissipation.

It's also embarrassing to encounter this situation. If you go to the repair shop to get it, you must remove the whole door panel. If you don't get it, you will feel uncomfortable. Generally, the guide groove on the window will be very small, which will be more troublesome to clean up, but it is not impossible.

You can prepare a plastic ruler and towel first, wrap the ruler with a towel, and slide back and forth in the guide groove to soften the originally hard rubber strip. Wait until you take out your ruler. You'll find a thick layer of dirt underneath, and it won't matter if you lift the window again.

Finally, although the car is bought for enjoyment, the parts on the car should be cherished at ordinary times. Of course, it doesn't mean to cherish it too much. As long as the usual maintenance is done well, it will definitely save a lot of money for future maintenance.
