Method for fabricating a vehicle door

A method for fabricating a vehicle closure member, the method comprising the steps of:

• providing a discrete lower door structure that is adapted to be pivotally coupled to a vehicle body and movable between a first position and a second position that substantially clears a door aperture;
• providing a discrete upper door structure having a pair of spaced apart frame rails that define a window aperture;
• installing a window member between the frame rails;
• installing a window regulator to the window member and the upper door structure, the window regulator being operable for moving the window member between a closed position substantially closing the window aperture and an open position at least partially clearing the window aperture, wherein the window regulator includes a pair of rack and pinion mechanisms and a pair of drive motors, each rack and pinion mechanism interconnecting a respective one of said frame rails and the window member and said rack and pinion mechanisms being spaced apart in a direction that is transverse to a direction in which the window member travels, each drive motor being independently coupled to a respective one of the rack and pinion mechanisms and operable for selectively translating the window member relative to the window aperture;
• and
• coupling the lower and upper door structures to one another after the step of installing the window regulator.
