Most cases are caused by issues with the window regulator guide channel. Simply clean the dirt inside the guide channel. At 4S shops or repair shops, when encountering slow window movement, strange noises, misalignment, or other malfunctions, the repair method is the same: replace both the regulator and the guide channel.

Window glass rising crookedly is a pretty common issue, and I've fixed quite a few similar faults. The usual causes are dirty or deformed glass guide channels – dust buildup can make the glass creak. If the guide rail screws are loose or the plastic clips inside the regulator are broken, the glass will rise unevenly. I recommend first checking the guide rails inside the door. If they're dirty, clean them thoroughly with a damp cloth to remove dust and debris, then apply some lubricant. If that doesn't work, inspect the regulator assembly to see if the mounting screws are loose, and tighten them. If the problem persists, it might be an issue with the motor causing uneven force. When driving normally, avoid forcing the glass to prevent further damage. This issue needs timely repair; otherwise, stuck glass can damage the vehicle. If you can't fix it yourself, go to a professional shop – safety first. Remember to clean your door panels regularly as preventive maintenance.

Last time my car window tilted while rolling up, I was also in a panic. The most common issue is usually with the guide rails—either misaligned or dirty, which can obstruct the window's movement. Motor failure or loose lift cables can also cause imbalance. I suggest starting with a simple check: open the door panel and inspect the guide rail grooves for any debris, clean them thoroughly, and apply lubricant. Tighten the mounting bolts to see if that helps. If not, check the wiring harness for loose connections. Avoid forcing the window during humid weather, as it can easily deform. Prolonging this issue accelerates component wear, so have the entire system inspected during routine maintenance. If your budget allows, hiring a mechanic saves time and effort while extending the vehicle's lifespan.

I've been dealing with this issue for years. Dirty or clogged guide rails or damaged lifting mechanisms are the main causes. Cleaning the guide rails and adding lubrication usually solves the problem. Check if the glass clips are loose, and make sure the bolts are tightened securely. If the tilt is severe, replacement parts may be needed. Timely repairs can prevent more serious malfunctions.
