Is it normal that the rear window of the Volkswagen CC can only open halfway?

[VonFernando]

Due to design reasons, the rear window of the Volkswagen CC can only open halfway and cannot be fully opened, which is a normal phenomenon. The reasons why some car models' windows can only be lowered halfway are as follows: 1. Window regulator damage: There is a regulator under the car window, which allows the window to move up and down flexibly. If the window regulator is damaged, the window may not fully open or close, or may not move at all. In this case, the window regulator needs to be repaired at a repair shop or 4S store, or replaced if necessary. 2. Lack of lubrication: If the internal parts of the window lack lubrication, friction may cause the window to not fully open or close. In this case, simply apply lubricant to the internal parts of the window. 3. Button malfunction: If the control button for the car window is damaged or not working properly, it cannot control the window's movement correctly. In this case, the window button needs to be repaired.
