The reason for the window glass lifting malfunction is deformation or damage to the glass mud slot; loose screws fixing the lifter; or damage to the window lifter. Below are the solutions for the window glass lifting malfunction and the classification of automotive glass: Solutions for Window Glass Lifting Malfunction: Turn on the ignition switch, pull and hold the switch upwards, continue holding for more than 3 seconds after the glass reaches the top, release the switch and immediately press and hold it downwards until the glass descends to the bottom for more than 3 seconds, then repeat the upward action once more. The initialization procedure is completed, and the window lifting function is restored. This method is effective for most vehicle models. If restoration is unsuccessful, it is necessary to go to a regular repair shop for inspection. Classification of Automotive Glass: Mainly divided into laminated glass, tempered glass, and regional tempered glass, which can withstand strong impacts. Automotive glass is classified by its position into four types: front windshield, side window glass, rear windshield, and sunroof glass.

I recently had trouble with my BMW's window not rolling up while driving, which was really frustrating. There could be several reasons for window failure, such as dust stuck in the switch button. I checked the button and it didn't respond, so I tried pressing it repeatedly a few times. Or there might be small stones or leaves stuck in the rails. I used a thin stick to gently poke and clean them, and it became much smoother afterward. Another possibility is a blown fuse cutting off the power. Check the fuse box, and if the one marked for the window is blown, replace it with a new one. Lastly, it could be due to motor aging, a common issue with older BMWs, requiring a visit to the repair shop for replacement. It's advisable to regularly clean the window gaps and spray some lubricant as a preventive measure, which can save a lot of hassle.

As a car owner experiencing window lift failure, my approach is to start with simple checks. First, test if the switch on the driver's door responds. If there's no response, open the hood and inspect the fuse box, replacing the corresponding window fuse to see if that helps. If the issue persists, consider that the window motor might be faulty. You can use a screwdriver to remove the door panel, unplug the motor connector, and test the voltage. If there's no power, check the wiring connections. Another common cause is dirt buildup on the tracks. Clean them with a soft cloth dampened with water and apply some track lubricant. If you can't fix it yourself, don't push too hard—seek professional tools or a mechanic for safer assistance.

Window malfunction while driving poses risks, such as the inconvenience of not being able to close the window during rain. My BMW once had this issue, mostly due to jammed tracks or poor switch contact. When dealing with it, immediately find a safe place to pull over, turn off the ignition, and restart the vehicle to try. If that doesn't work, check if the switch buttons are loose and clean any dirt from the tracks. Prevention is key—avoid dust buildup and regularly spray some rust inhibitor to maintain smooth operation.
