How to replace the rear door window regulator on 2004 Buick LeSabre?

The replacement process of the rear door Window Regulator starts with removing the door trim panel and door module together with the water deflector. Place tape across the window before performing four revolutions of adjustment to the window clamp fasteners and partially lowering the Window Regulator. To change the Window Regulator pull the power Window Motor electrical connector besides removing fasteners (1,2,3) between the regulator and inner door panel. Then glide the regulator out of the door by rotating its motor end toward the door front and its top to the lower rear corner before pulling the unit through the front access hole at the door panel. Routine installation requires the Window Regulator to enter the door through the front access slot after tightening fasteners in this sequence: first fastener at 9 n.m (80 LB.IN) then the second fastener at 9 n.m (80 LB.IN) and finally the third fastener at 9 n.m (80 LB.IN). After removing tape from the window you can insert it into the Window Regulator clamps before plugging the power Window Motor electrical connector. Start the engine and elevate the window to full closure before securing both clamp fasteners at 11 n.m (95 lb in). Check the window function and its sealing quality before reinstalling the water deflector and door module followed by the door trim panel.
