Why Does the Car Window Automatically Roll Down and Open?

[HopeAnn]

There are several specific reasons why a car window may automatically roll down: 1. Window regulator failure: The retaining cable of the window regulator is damaged. It is recommended to replace and reinstall a new one. 2. Issues with the window anti-pinch function: The car is equipped with an anti-pinch feature. When the window encounters significant resistance while rolling up, the anti-pinch function may be mistakenly triggered, causing the window to automatically roll down. This could be due to problems with the sealing strip or the window regulator. 3. Faulty control button box: Moisture in the control button box may cause system errors. 4. Obstruction in the window guide channel: If there is excessive resistance in the window guide channel when the window is rolling up, the motor's current increases. If the window does not fully close, the anti-pinch function will activate, causing the motor to reverse. This issue requires cleaning or replacing the window guide channel.
