What is the reason for one electric car window malfunctioning?
3 Answers
Generally, the reason for one electric car window malfunctioning is deformation or damage to the glass channel. More reasons and solutions are as follows: Additional reasons for malfunction: Loose screws fixing the window regulator or damage to the window regulator itself. Solutions: Turn on the ignition switch, hold the window switch in the up position, and keep holding it for more than 3 seconds after the window reaches the top. Release the switch and immediately press and hold it again to lower the window to the bottom, keeping it held for more than 3 seconds. Repeat the upward motion once more to complete the initialization process, restoring the window's functionality. This method works for most car models. If the issue persists, it is recommended to visit a professional repair shop for inspection.
I've been in car repair for years and encountered all kinds of window issues. For a single window failure, the most common cause is switch malfunction, where oxidized or worn copper contacts lead to poor connectivity. Secondly, the motor might be burnt out, especially when operated frequently during rainy days. Track blockage is another major reason, as dust or aging rubber seals make window movement difficult. Short circuits or blown fuses are also common issues. If other windows work normally, it indicates the problem isn't with the overall circuit. Safety first—it's recommended to check before starting the car. Use a multimeter to test switch or motor voltage first, and avoid forcing the window to prevent further damage. For repairs, choose authorized shops to ensure durability. Replacing fuses or lubricating tracks yourself is simple and worth trying first.
My car's passenger window often gets stuck, and upon inspection, I found the switch button won't pop back up. There are many possible reasons for such malfunctions: it could be a blown fuse, which is cheap to replace; motor aging or broken wires, especially at the door hinge area; or dirt buildup and lack of lubrication in the tracks. Malfunctions while driving can affect safety, so it's best to stop and diagnose the issue slowly. I make it a habit to carry a bottle of window lubricant for prevention and regularly clean the tracks to reduce problems. The switch tends to act up more frequently during humid weather. Minor issues can be fixed with DIY solutions, but major problems like motor failure require professional repair to avoid secondary damage. Remember not to force the window up and down too frequently to extend its lifespan.
