What is the reason for the ineffective car window lock button?

In this case, the reason is a malfunction in the power window module, which can be resolved by replacement. Below is relevant information about the window lock button: 1. Function: The window lock button is a safety feature currently available in many car models. When the driver activates this function, the rear power windows of the vehicle are forcibly locked, preventing passengers in the rear from opening them. This helps minimize the risk of children opening the windows on their own and sticking their heads or hands out. Window lock means that once locked, only the driver can control all four windows. 2. Working Principle: Currently, the lock-up clutches used in cars can be roughly categorized into hydraulic, centrifugal, and viscous types based on their working principles, with the hydraulic type being the most common. The hydraulic lock-up clutch utilizes the driving oil pressure generated by the hydraulic system in the automatic transmission to lock the pump and turbine of the torque converter together.
