The reasons for the failure of the driver's side window to roll up or down may include damage to the window lift motor; overheating protection of the motor; or excessive resistance in the glass guide channel. In such cases, it is best to have it inspected and repaired at a 4S shop as soon as possible. Window lift motor damage: If there is a burnt smell or unusual noise inside the door panel when holding down the window button for a long time, it is likely that the window lift motor components are damaged. In this case, it is recommended to directly visit a 4S shop or auto repair shop to replace the window lift motor. Motor overheating protection: To protect the power supply circuit, most window lift motors have an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, causing the window to fail to roll up or down. This is a normal phenomenon and does not require repair. Excessive resistance in the glass guide channel: The door glass guide channel is a detail that is often overlooked. During use, dust can accumulate in the glass guide channel, increasing resistance, which may over time make it difficult for the glass to roll up. It is necessary to clean the dust from the glass guide channel.
It's inevitable to encounter window lift failure after driving for a long time. I had the same issue last time and found out it was just a blown fuse, which was easy to fix. A simple test can help diagnose the problem: if the switch button shows no response at all, it's likely a blown fuse in the engine box; if there's sound from the button but the window doesn't move, the motor might be faulty; if there's no reaction whatsoever, it could be a short circuit or a broken switch. Foreign objects stuck in the window track or rust can also make the window hard to lift. I usually try replacing the fuse first—most cars have a fuse box under the driver's seat for quick replacement. However, don’t overlook safety concerns, as driving with frosted windows in winter can be dangerous. Address the issue immediately to avoid problems on the highway. If you're unsure, it's best to visit a professional mechanic for a thorough check—it saves time and hassle.
