Why do all four car windows suddenly stop working?

[CarlosLee]

If all four car windows suddenly stop working, it could be due to issues with the power supply circuit of the window glass, or aging rubber guide channels outside the windows, or dust accumulation on the rubber strips. Excessive dust buildup can cause excessive resistance, preventing the windows from functioning properly. The owner can use a wet towel wrapped around chopsticks to reach into the guide channels and slide back and forth to remove dirt. If the battery is disconnected or the power or ground wire of the window control module is disconnected during maintenance, the initialization data of the windows will be lost after restarting the engine, causing the windows to malfunction. In this case, the system needs to be reset. Turn on the ignition switch, pull and hold the switch to raise the window, continue holding for 3 to 5 seconds after the glass reaches the top, release the switch and immediately press and hold it again, wait for the glass to descend to the bottom for 3 seconds, then repeat the raising action once more to complete the initialization procedure.
