WG1664330003 Electric Glass Lifter Use for SINOTRUK HOWO HOHAN FAW SHACMAN DONGFENG BEIBEN FOTON Spare Parts

The WG1664330003 Left Electric Window Regulator Assembly is a genuine OEM window lift mechanism designed for the driver’s side front door of SINOTRUK (China National Heavy Duty Truck Group) heavy-duty trucks, particularly within the HOWO A7, T7H, and SITRAK C7H series. This electric window regulator enables smooth and reliable vertical movement of the door glass, supporting both manual control and optional one-touch auto-up/down functions depending on vehicle configuration.

Built with durability in mind, this dual-track wire-rope type mechanism features high-strength steel rails, reinforced nylon sliders, and precision-tensioned steel cables to withstand the rigors of long-haul operations, extreme temperatures, and constant vibration. While some versions are sold as a complete unit with motor, others are supplied as a regulator-only assembly (without motor) — buyers should verify package contents before purchase.
