4W Universal 4-Door Auto Window Closer
Model 4W — a universal smart window closer that adds automatic window closing to 12V vehicles: when the car is locked, the module rolls up all four windows automatically. It works with the vehicle's original window motors, connects through a multi-pin harness, and draws only 6 mA on standby — a practical add-on for keyless entry and security installations.

Many vehicles leave the windows open when the driver forgets to close them before locking. This 4-door window closer module solves that: once installed, locking the car triggers the module to roll up all four windows automatically. The unit drives the vehicle's original window motors — window lift speed and behaviour follow the original vehicle, with nothing to adjust.
For installers and retailers it is a natural add-on sale alongside remote start, keyless entry and car alarm installations: the target customer is the same, the installation point is the same, and the universal design means one SKU can be stocked for a wide range of 12V vehicles.
