What to Do When the Car Windows Roll Down by Themselves After Locking?

Adjust the number of towel layers according to the width of the guide channel, then slide the towel up and down inside the channel to clean it. The towel can be removed and washed until it is clean. After cleaning, spraying some dashboard wax in the glass guide channel will help. However, this can only solve most of the problems. For issues caused by the motor or mechanism of the window regulator, it is necessary to consult a professional mechanic for repairs.
Recently, my car also had a similar issue where the windows automatically rolled down after locking, which was quite annoying. I think the most common causes are poor contact in the window switches or water ingress. When I encountered this before, I would first try locking and unlocking the car again to see if the windows would roll back up normally. If that didn't work, I would disconnect the negative terminal of the car battery, wait for about ten minutes, and then reconnect it to reset the window control system. If the problem persisted, it might be due to a blown fuse or a faulty module. I recommend taking it to a professional auto repair shop or a 4S dealership to check the control module and wiring, rather than attempting DIY repairs that could cause more damage. It's also important to ensure the windows are fully closed when parking to avoid moisture causing switch short circuits, and regular lubrication checks for the windows are essential. If not handled properly, this issue can lead to water leakage inside the car or battery drain, so the sooner it's addressed, the better.
As a new driver, I've also encountered the strange phenomenon of windows opening by themselves after locking the car, which was quite unsettling at the time. After researching, I found it might be caused by control sensor malfunctions or voltage instability, such as insufficient battery power or ECU software bugs. For troubleshooting, I tried pressing the window button several times to confirm its status, then checked the fuse box to see if the corresponding window fuse was blown, replacing it with a new one of the same type if necessary. If that didn't work, I attempted to briefly disconnect the battery cables to reset the system. Developing a habit of pulling the window switch after parking and avoiding rain soaking the control panel can effectively prevent this issue. If it happens repeatedly, it's crucial to visit a repair shop for diagnosis promptly to prevent affecting door locks or safety systems. Remember not to ignore the problem during rainy days, as it could easily damage the car's electronic components.
