What Causes Power Window Failure?

[JasperLee]

Excessive dust accumulation in the window guide channels causes jamming during window operation. Below is relevant information about one-touch power window functionality: 1. Enhanced Safety: One-touch power windows allow complete window movement with a single button press, a feature typically found in mid-to-high-end vehicles. This design prioritizes convenience for occupants while preventing driver distraction during window operation, thereby improving safety. 2. Anti-pinch Protection: Different vehicle models may use varying symbols for this function (most commonly marked "Auto"), sometimes labeled as "one-touch lock button." The operational principle remains identical - long-pressing the lock button raises all windows simultaneously, while holding the unlock button lowers them. These systems universally incorporate anti-pinch mechanisms that automatically halt and reverse window movement upon detecting obstruction between glass and frame, preventing potential injury risks.
