What is the reason for the inability to raise or lower the right rear window glass?

[SanEzra]

The reasons for the inability to raise or lower the right rear window glass are as follows: Aging of the window seal: The window seal (including the inner strip) may be aged, dirty, or deformed, which can create resistance when raising or lowering the glass. Generally, if the seal is aged or deformed, it is best to replace it with a new one. If it is just dirty, cleaning it should suffice. Spraying some dashboard wax or applying talcum powder (to act as a lubricant) on the window seal can often yield good results. Dirty window regulator track: The window regulator track may be too dirty. This is also a lubrication issue. Cleaning the window regulator track and applying grease can eliminate the problem. Low battery charge: Check if the issue is due to low battery charge. When raising or lowering the window without the engine running, the power is drawn from the battery. If the battery charge is too low, difficulty in raising or lowering the window may occur.
