What Causes the Car Window Glass to Malfunction When Rolling Up or Down?
3 Answers
The reasons for the malfunctioning of car window glass when rolling up or down are as follows: 1. The mud groove of the glass is deformed or damaged. 2. The screws fixing the lift mechanism are loose. 3. The window regulator is damaged or there is a deviation in the installation position of the guide rail. The most direct solution for malfunctioning car window glass is to have it inspected and repaired at a 4S shop as soon as possible. The general solutions for car window glass lifting issues are as follows: 1. Turn on the ignition switch, pull the switch up and hold it. 2. After the glass reaches the top, continue to hold the switch for more than 3 seconds, then release and immediately press and hold it again. 3. Let the glass descend to the bottom, wait for more than 3 seconds, and then repeat the lifting action once more. 4. Once the initialization procedure is completed, the window lifting function will be restored.
Once while I was driving on the road, the car window suddenly rolled down and wouldn't go back up, which gave me quite a scare. Later, when I took it to the repair shop, they found that a lot of dust and small stones were stuck in the window track, causing the glass to jam and the window to malfunction. They also mentioned that this is quite common, especially for older cars or those frequently parked in dusty areas. The motor in the window lift system can also fail due to overheating or wear, and if the switch button has poor contact, it can similarly prevent the window from moving. If you notice the window moving slowly or not at all, it's best to try cleaning the track yourself with a soft cloth. Don't underestimate this issue—a malfunctioning window not only affects ventilation while driving but can also let water into the car during rain, damaging the interior. After learning my lesson, I now perform a quick check on the window tracks every week to ensure they're clean and lubricated, making the car much smoother to drive.
There are quite a few reasons why car windows get stuck when rolling up or down. I've encountered this several times while fixing my own car. The most common issue is with the switch button – the internal contacts may rust or wear out, preventing the signal from getting through. Motor failure is another major cause; it's responsible for driving the glass up and down, and prolonged use can lead to aging or overheating, causing it to stop working. If dust or debris gets into the glass tracks, it can directly block the movement path, making the window less responsive. Additionally, broken wiring or a blown fuse can interrupt the power supply. I think the specific causes can vary by car model – older cars are more prone to mechanical part failures, while newer cars might experience electronic system malfunctions. If you run into this problem, don't force the switch; listen for unusual sounds, which can help you preliminarily determine whether it's a motor or track issue. Checking the fuse is also crucial – it's located in the fuse box under the hood and can be easily replaced. For more serious cases, it's best to visit a professional shop to avoid minor issues escalating and affecting driving safety.
