What Could Be the Reason for Three Car Windows Suddenly Failing to Roll Up or Down?

[Ashlyn]

Three car windows suddenly failing to roll up or down may be due to issues with the power supply circuit for the window glass or aging rubber guide channels outside the window, along with dust accumulation on the rubber strips. Below are the relevant explanations: 1. Rubber Guide Channels: Window glass misalignment or operational issues are often caused by aging window glass guide channels or excessive dust buildup, leading to increased resistance and preventing normal window operation. You can use a wet towel wrapped around chopsticks to clean the guide channels by sliding back and forth to remove dirt. 2. Power Supply Circuit: If the car battery is disconnected or the power or ground wire for the window control module is disconnected during maintenance, severe battery discharge may cause the window initialization data to be lost after restarting the engine, rendering the windows unable to operate normally. In this case, the system must be reset.
