Elimination of abnormal sound in driver’s door

September 22, 2024

There has been a noise in the driver’s door for a long time. I always thought that the door screw had fallen off. Every time the car turns, there will always be a knocking sound. It is really unbearable, so I decided to go to 4S to find out the reason.

When I arrived at the 4S shop, I briefly explained the situation to the master. There was no doubt that the door panel had to be removed to find the crux of the problem. This is the third time that the driver’s door has been removed. The first time is to replace the exterior mirror, and the second time is to replace the window lifter. The process of removing the car door was still quite complicated, and the young master struggled for a while.

After the door was completely disassembled, no screws or other objects fell out. Everyone was very surprised. Then the master used it again and shook the door, but the sound was still there. I took a photo with my mobile phone and found that there was something else inside the door panel. After taking it out with great effort, I found that it was a spring and a window lifter that had not been removed completely. When removing the old lifter, it was not removed completely, which made me dizzy.

Since it was not caused by my own reasons, the 4S shop was okay, and there was no charge for solving the problem this time. After a lot of trouble, the problem was solved. Free testing was also done.
