Abstract
A window lift mechanism for raising and lowering a window in a vehicle door includes a support bracket mounted to the window and a motor supported on the support bracket. A pair of parallel, vertical racks are mounted to the door and are positioned immediately adjacent the window. Pinion gears driven by the motor are supported on the support bracket and engaged with the rack to permit vertical movement of the window.
