What are the reasons for car window glass not being able to rise?

[RichardDella]

Here is the relevant introduction about car window glass being unable to rise: 1. Electrical failure: When the car battery is disconnected or the window control circuit is disconnected during maintenance, we only need to reset the window system; Turn on the car ignition switch, hold the switch to keep the window in the rising state, wait for the glass to rise to the top and continue to hold for more than three seconds, release the lifting switch and immediately press it to keep the window in the descending state, lower the window glass to the bottom and wait for more than three seconds, and then repeat the window rising action once again to complete the reset of the window lifting system. 2. Mechanical failure: The problem is mostly caused by excessive dust in the window glass groove, which increases resistance and hinders the normal operation of the window lifter. In this case, we need to go to a professional car repair shop for cleaning. If the window still cannot be lifted after cleaning, it means that the window lifter of our vehicle is damaged and needs to be replaced.
