What is the reason for the one-touch power window not working?
2 Answers
The sudden failure of the one-touch window function is likely caused by a momentary loose connection or power interruption in related components. Simply resetting the one-touch window function should resolve the issue. Here is some relevant information: Car Window: The car window is an essential part of the vehicle body, designed to meet the needs of interior lighting, ventilation, and visibility for drivers and passengers. Location: Windows are categorized based on their installation positions: front and rear windshields, side windows, and door windows. The design, structure, and quality of car windows significantly impact the driver's visibility, passenger comfort, aesthetic appearance, and aerodynamic characteristics. Typically, car windows are constructed as curved, sealed units. Rubber sealing strips are used to connect the window frame and the glass, providing both sealing and cushioning effects to prevent damage to the windshield in case of body deformation under stress.
Recently, my car’s rear window also had this issue. After some research, I found there are quite a few possible causes. The most basic one is that the window initialization was lost—meaning the system forgot the set position after a power outage, requiring a manual reset: hold the button upward until the window is fully closed, then keep holding for another five seconds. Similarly, pull it down to the bottom and hold for five seconds. Worn-out switches can also be the culprit, especially if the internal metal contacts are faulty after long-term use. Another possibility is debris like leaves or sand stuck in the window tracks, increasing resistance and triggering the anti-pinch function, which then switches to manual mode. Additionally, if you’ve installed accessories like a dashcam that modified the wiring, it could interfere with the control module’s signals. From personal experience, try resetting first; if that doesn’t work, check the tracks and switches.
