To begin, remove the armrest from the door interior trim panel by unscrewing two screws. Next, use a wire with a small hook to extract the securing clip behind the window regulator handle and then remove the handle. After that, extract the screw from the door lock interior remote control handle and take off the cover plate. Insert a flat blade or your fingers between the trim panel and the door to pull out the panel securing clips. Carefully peel away the self-adhesive waterproof sheet and, at the base of the window opening, prise out the inner weatherstrip. Temporarily refit the window regulator handle and lower the glass fully, then remove the screws holding the glass holder to the regulator arm. Prise out the outer weatherstrip with a screwdriver, pull the door glass upward, and remove it from the door cavity by turning it. Extract the roller guide and regulator mounting screws to withdraw the complete regulator assembly from the lower aperture in the door interior panel, and renew the regulator if it is worn. If fitting a new glass, attach the holder to its bottom edge accordingly, and grease the regulator before refitting. The refitting process is the reverse of removal, ensuring that if the clip on the inner weatherstrip has separated from the trim panel, it is turned through 90° with a screwdriver to reconnect it. For smooth operation of the window regulator and glass, three points of adjustment are available: the roller guide mounting screws, the glass holder to regulator arm screws, and the front and rear glass slide channel screws. Release the screws and adjust the components until the glass moves up and down smoothly without judder or misalignment. When refitting the regulator handle, fit the clip into the handle and then firmly bang the handle onto the splined spindle of the regulator.
