To remove the front door window, start by taking off the door trim panel. Reconnect the electric window switch or window winder handle, then lower the glass until the door glass retaining bolts are visible through the access holes in the inner panel. Unscrew the glass retaining bolts, lift the glass, and remove it from the door. For refitting, reverse the removal process, ensuring the glass retaining bolts are tightened securely and the door trim panel is reattached. For the front regulator, after removing the window glass, disconnect the wiring plug from the motor on electric window models. The regulator is held by five bolts for manual windows or six for electric windows; remove these bolts and take out the regulator. During refitting, lubricate the moving parts of the regulator with multi-purpose grease and check the operation of the mechanism before reattaching the door trim panel. For the rear window, remove the door trim panel and open the window fully. Unclip the door sliding glass runner from the top and sides of the window frame, then pull it upwards to remove. Pull off the door seal at the upper rear corner and take out the window rear guide channel top screw. Remove the two bolts securing the base of the rear guide channel and slide it out of the door. Slide the rear fixed glass and its rubber seal forwards to remove it, and if needed, detach the rubber seal from the glass. Move the sliding glass rearwards and upwards to free it from the regulator, then lift it out of the door. For refitting, check the operation of the window regulator mechanism before reattaching the door trim panel. For the rear regulator, after removing the window glass, disconnect the wiring plug from the motor on electric window models. The regulator is secured by two bolts for manual windows or three for electric windows; remove these bolts and withdraw the regulator. During refitting, lubricate the moving parts of the regulator with multi-purpose grease and check the operation of the mechanism before reattaching the door trim panel.
