In order to access the interior door handle, the door trim panel that holds the clips should be levered out and the cellophane insulating panel peeled off, taking care not to damage clips on the trim. In the case of the front door window glass, place it in such a way that you can reach to the glass clamps, pull out the inner sealing strip, loosen the window clamp nuts, and get the glass out of the window through retrieving it on the top. In the case of rear door window glass, pull the lower window, loosen the screws holding it, pull off the window guide rail, loosen the clamp nut, and remove the glass. In case it is required, detach the fixed window on the sealing strip. In the case of the front window regulator, once the glass has been taken out, dislodge the retaining clip, unplug the wiring on the electric models, unscrew the retaining bolts and pick out the regulator mechanism. In the case of the rear window regulator, repeat the process of removing the glass, disconnecting the wiring in case it is present, loosening the retaining bolts and then manipulate the regulator out. To install, fit the front window glass, attach it to the regulator clamp, apply the inner sealing strip, test the window operation and fix the insulating panel and trim. In the case of the rear window glass, simply make sure that the fixed window is in place, clamp the glass using the regulator clamps, and mount the window guide rail and screw it in. In the case of the front window regulator, position it, fix and attach the retaining bolts, and possibly reconnect on the wiring. Lastly, in the case of the rear window regulator, position and install the retaining bolts, reconnect the wiring (where necessary) and install the glass.
