2005 Buick LeSabre Sunroof Handle

You should cycle the sunroof window from the fully open to the closed position, loosen the 4 adjusting screws, center the window front to rear in the opening, and adjust the front of the sunroof window from flush to 1 mm (0.04 in) below and above the top surface of the roof panel, cycle the sunroof window through all of the positions, verify the sunroof window fore/aft adjustments, verify the front and rear height adjustment and readjust the sunroof window, if necessary.

You should remove the sunroof window, fabricate a gage 46.8 mm (1.84 in) wide, set the gage into the track near the rear of the opening between the move driver slide and the bracket, move the driver slide fore or aft to get the proper setting, install the sunroof window, install the sunroof actuator and operate the sunroof through all functions to ensure proper operation.

You should position the sunroof window into the opening, install the sunroof window screws and adjust the sunroof window.

You should open the sunshade, remove the sunroof window screws on both sides and remove the sunroof window, being careful not to scratch the roof surface.
