2003 Infiniti G35 and the driver side window drops halfway down when rolled up Why?

The issue of the driver side window of a 2003 Infiniti G35 dropping halfway down when rolled up may be caused by a faulty window regulator or a malfunctioning power window switch. Additionally, a misaligned window or damaged weatherstripping could contribute to this problem. It's also possible that the anti-pinch feature is engaging if it detects resistance, causing the window to stop. A thorough inspection by a professional can help diagnose and resolve the issue.
