Why can the car window only go down but not up?

If the car window can only be lowered but not raised, check for debris in the window track or a malfunction in the window regulator. Here are the detailed explanations: 1. Window Regulator: The window regulator is the mechanism that raises and lowers the car door window glass, mainly divided into electric window regulators and manual window regulators. Nowadays, many car door window glasses are generally operated by button-style electric lifting mechanisms, using electric window regulators. 2. Solution: Turn on the ignition switch, hold the switch in the upward position, and after the window reaches the top, continue holding for more than 3 seconds. Release the switch and immediately press and hold it again to lower the window to the bottom for more than 3 seconds. Then, repeat the upward action once more to complete the initialization procedure, restoring the window's lifting function. This method is effective for most car models. If the function is not restored, it is necessary to take the car to a professional repair shop for inspection.
