What is the reason for the main driver's window button not responding?

[SanMakayla]

The reason for the malfunction of the main driver's window button is that the copper sheet on the button circuit board loses its elasticity under external pressure, resulting in failure. Here is some information about car windows: 1. Introduction: Car windows are openings set on the four walls of the vehicle compartment to block wind and rain while maintaining visibility. They are generally made of glass materials, which have evolved significantly over time. Most automotive glass is made of silica glass, with silicon dioxide content exceeding 70%. 2. Types: Car windows are typically divided into four categories: front and rear windshields, ventilation windows, heat-insulating side windows, and sunroofs. The front and rear windows of vehicles usually use curved glass that provides good visibility and aesthetic appeal, embedded in the window frame with rubber sealing strips or adhered with special adhesives.
