To replace the front window glass, start by removing the door inner trim panel and plastic sealing sheet. Temporarily reconnect the electric window switch and lower or raise the window to access the two bolts securing the lower edge of the glass to the Window Regulator mechanism. Support the glass and undo the bolts, then disengage the glass from the Window Regulator and lower it to the bottom of the door. Carefully remove the inner window channel/seal from the upper door frame, ensuring not to damage it. Next, undo the bolt securing the rear guide channel to the door, disengage it, and remove it through the door aperture. Raise the glass at the rear, tip it forward, and withdraw it from the outside of the door frame. When refitting, ensure the glass moves satisfactorily in the channel and guide channels, check the window mechanism's operation, and reattach the door inner trim panel. For the front Window Regulator, first remove the front window glass, then disconnect the wiring connector from the motor and undo the securing bolts to manipulate the complete assembly out through the door aperture. If needed, separate the motor from the Window Regulator. During refitting, ensure the front window glass is reattached, check the window mechanism's operation, and reattach the door inner trim panel. For the rear window glass, fully open it and remove the door inner trim panel and plastic sealing sheet. Carefully remove the inner window channel/seal from the upper door frame, then temporarily reconnect the electric window switch and raise the window to access the bolts securing the lower edge of the glass. Support the glass, undo the bolts, and disengage it from the Window Regulator, raising it at the rear and withdrawing it from the inside of the door frame. When refitting, ensure the glass moves properly in the channel and guide channels, check the window mechanism's operation, and reattach the door inner trim panel. For the rear Window Regulator, remove the door inner trim panel and plastic sealing sheet, then temporarily reconnect the electric window switch and adjust the window to access the bolts. Support the glass, undo the bolts, and slide it to the top of the window frame, taping it in position. Disconnect the wiring connector from the motor, noting that the rearmost upper Window Regulator bolt does not need to be completely removed. Undo the securing bolts and manipulate the motor/Window Regulator assembly out through the door aperture, separating the motor from the Window Regulator if necessary. During refitting, ensure the window glass is reattached and tightened, check the window mechanism's operation, and reattach the door inner trim panel.
