What is the cause of abnormal noise in the window glass?

[China Glass Net] The problem of abnormal noise of automobile window glass, I believe that most car owners have encountered it, then everyone knows what is the cause of abnormal noise of window glass lifting, I believe most car owners are not very clear, then the following Let’s take a look.

1. It may be caused by the aging of the glass sealing strip. After the sealing strip is aged, the frictional force will become larger, and abnormal noise will occur. If this is the case, it will be more obvious in the summer, because the aging seal will expand more and more friction after the sun is exposed, so the noise will be more serious.

2. It may also be that the gap between the glass and the sealing strip is too dirty, and the particles in the dust rub against the glass to produce an abnormal sound.

3. It may also be because the glass rails are dirty.

4, caused by the failure of the lifting motor.

Kind of situation.

First, raise the glass with water to flush the gap between the window and the sealing strip, dry it and lower the window. then. Look for a discarded or other card, then look for a piece of wet flannel and insert it into the gap of the seal to wipe it repeatedly. Spray the lubricant after drying.

If it is the third case, you have to remove the door panel and spray the glass rail groove with lubricant or bubble water. If you have strong hands-on ability, you can do it yourself. If you are too lazy to move, you should spend money to let others do it.

In short, the reason for the glass to raise and lower the abnormal sound, you have to know, even if you do not do it yourself, you can prevent the 4S shop from being pitted. Many people have changed the motor or seal strip directly to the 4S shop because of the abnormal noise of the glass. Even some have been replaced by the glass lift assembly. In fact, it is a dusty thing, and it will be fine.
