What are the reasons for a car window not closing?

[McMolly]

Window glass not closing may be due to the following reasons: Switch malfunction: If the switch is faulty, it can only be replaced. If the electronic device is not functioning, check the relevant fuse. If the fuse is damaged, replace it. Track blockage or rubber seal aging: Most cases of window glass not moving up or down are due to mechanical jamming. Cleaning the track and applying some lubricant can resolve the issue. If the problem is caused by aging or deformed rubber seals, new seals need to be replaced. If it's just dirty, cleaning is sufficient. Spraying some dashboard wax on the window seals or applying talcum powder (for lubrication) can also be very effective. Window regulator switch damage: The car window switch is one of the most frequently used switches in a car, used almost every time you drive, so the probability of damage is high. In this case, simply replace the entire window regulator switch.
