What is the reason for the car window not going up?

Car window cannot be raised due to a malfunction in the window regulator switch. Below is an introduction to the window regulator: 1. Introduction: The window regulator is the lifting device for car door and window glass, mainly divided into two categories: electric window regulators and manual window regulators. Nowadays, many car door and window glasses are generally operated by button-type electric lifting methods, using electric window regulators. 2. Composition: The electric window regulator for cars is mostly composed of a motor, reducer, guide rope, guide plate, glass mounting bracket, etc. The master switch is controlled by the driver to open and close all door and window glasses, while the individual switches on the door handles inside each door are controlled by passengers to open and close respective door and window glasses, making operation very convenient.
I've encountered the issue of windows not rolling up several times. The most common cause is a blown fuse. Just locate the corresponding fuse in the engine compartment's fuse box and replace it to fix the problem. If the switch button doesn't respond when pressed, it might be due to aging internal contacts, so you should test whether the connection is good. If the window motor is old and lacks power, the glass won't move, and you'll hear a buzzing sound. Small stones or accumulated dust in the tracks can jam the glass, but spraying some lubricant can loosen it. In winter, frozen rubber seals can be a big problem, causing the glass to stick and not move at all. Additionally, if the anti-pinch mechanism is too sensitive, it may activate self-protection and stop the glass. Short circuits or broken wires affecting power supply are best checked with a multimeter to see if the voltage is normal. I've also experienced weak window operation due to low battery power before. A simple method is to try replacing the fuse first. If that doesn't work, don't delay—head to a repair shop quickly to avoid rainwater damaging the interior. Safety is crucial, so don't get distracted while driving to fix it, as it could lead to accidents. Spending a bit more to hire professionals can save you a lot of hassle.
