How to Fix a Tilted Window When Rolling Up?

[ReedLee]

If the window glass is misaligned when rolling up, aside from potential issues with the guide channel, it could also be due to loose screws securing the glass, which may cause this problem. Another possibility is a malfunctioning window regulator. If the motor is aged and lacks sufficient power, it may struggle to lift the window when encountering slight resistance. In such cases, replacing the regulator motor is necessary.

Common reasons for car window glass tilting when rolling up include debris stuck in the tracks, loose lift cables, or motor issues. Last time I encountered this, I first tried fixing it myself: using a damp cloth with soapy water to clean the guide rails and slots, as dust buildup can easily cause the glass to tilt. If that didn’t work, I’d check if the window regulator cables were worn or broken—sometimes just tightening the screws helped. In the end, I had a repair shop replace a new track, which cost some money but completely solved the problem. To prevent this, avoid piling items near the door edges and keep the tracks clean. Otherwise, long-term misalignment may damage the seals or lead to leaks and drafts.
