Upgraded Performance: Upgraded internal components of the window switch driver side to address issues such as driver window failure. First, the latest chip design reduces power consumption and prevents battery drain. Second, improved circuit protection minimizes the risk of power failure under load to ensure smooth operation. In addition, we have optimized the communication with the door control system to avoid false signals and enable the windows to be raised and lowered sensitively
Sturdy and Durable: The housing is made of ABS, which is resistant to abrasion and corrosion and can be used for a long time. Each button is rigorously tested before leaving the factory for silky smooth operation, no jams and no noise. Conforms to the original standard pin, plug and play
