Why doesn't the window roll down when holding the unlock button on a Volkswagen?

When holding the unlock button on a Volkswagen and the window doesn't roll down, this may be due to the one-touch window function failing and needing to be reinitialized. It is recommended to contact a 4S shop. How the one-touch window key works: The key emits a weak radio wave, which is received by the car's antenna. The electronic control unit identifies the signal code, and the system's actuator (motor or electromagnetic coil) then performs the open/close action. The maintenance methods for one-touch windows are as follows: 1. Keep the window glass clean: The most common issue with power windows is the hardening or accumulation of dirt in the rubber tracks of the glass, causing the glass to move unevenly or get stuck. In such cases, it is important to keep the window glass clean. Dirty glass not only affects appearance and visibility but may also interfere with the operation of the power window. 2. The glass must be kept clean regularly: To prevent rainwater from entering the car, there is a rubber strip attached to the top of the window frame, which is also in frequent contact with the glass. When the glass is dirty, friction with the rubber strip increases, affecting the window's operation. Therefore, the glass must be kept clean regularly.
