How to Fix a Non-Returning Car Button?

[IsabelaRose]

Use a hex screwdriver to unscrew the bolts and pull outward firmly to remove the entire window button assembly. Disconnect one black and one white wiring harness, take photos of the black and white wires, and note their positions to avoid incorrect reconnection. Use a small screwdriver or tweezers to pry up the flattened copper piece on the button circuit board, lifting it slightly higher; then reinstall it as it was. If the window button still does not return after trying the above methods, it is recommended that the owner take the car to a professional repair shop for inspection and repair.
