Window Regulator, Rear Driver Side

One should start the process of Window Regulator replacement by dismantling the door trim panel then the water deflector. The next step is to extract the energy absorber retainers combined with the energy absorber from the door before removing the coverings that shield the holes for the regulator bolts. Remove window to regulator bolts to disconnect the window from its regulator before elevating it to the highest point as support. First disconnect the electrical connector from the regulator motor and then loosen the upper bolt which retains the regulator to the inner door. First disconnect the lower regulator bolt then release the motor from the door through the nut connection. Raise the regulator/motor eventfully to unlock the upper bolt from the door and move the regulator upper segment in a forward direction. The first step involves removing the lower part of the regulator through the door opening before removing the upper bolt from the regulator and Window Regulator motor from the same component. Install the Window Regulator motor to the regulator by fastening it partially to the upper bolt of the regulator. To install the regulator insert it through the door opening with a semi-horizontal seating position before fully positioning it ahead in the door cavity before rotating to vertical. Fasten the regulator onto the door sheet metal by using the already existing upper bolt. Insert the nut to retain the motor on the door and tighten it to 9 n.m (80 lb in) before securing the regulator to the door using upper and lower bolts (3, 4) tightened to 10 n.m (88 lb in). Return the electrical connector to the regulator motor followed by uninstalling the window support. Drop the window onto the side guide of the regulator. First stabilize the regulator window carrier bolts with loose tightening. After putting the window in the full up position within the run channels maintain its position. Following this install the door energy absorber along with its retainers. End the installation by putting on protective covers that should cover the regulator bolt holes together with the water deflector and the door trim panel.

The process of replacing the rear side door Window Regulator starts with removing the door trim panel and water deflector as well as the energy absorber retainers together with the energy absorber from the door. You need to remove the brittle plastic covers from regulator bolt openings before taking out the window to regulator bolts. Move the window to its maximum height before disconnecting the electrical power connection from the regulator motor. Begin by loosening the upper retaining bolt of the regulator from the inner door and remove the nut retaining the motor to the door before extracting the lower regulator bolts. First raise the regulator/motor upward to let out the upper bolt from the door before rotating the upper portion of the regulator forward for removal by starting with the lower portion. Break free the upper bolt from both the regulator and the Window Regulator motor that is attached to the regulator. You should mount the Window Regulator motor onto the regulator and insert part of the upper bolt into the regulator at this step. Insert the regulator through the door opening with a semi-horizontal orientation and guide it into complete forward placement in the compartment before turning it into a vertical position. Install the regulator onto the door sheet metal by using the previously installed upper bolt. Insert the nut which retains the motor to the door while tightening it to 9 n.m (80 lb in). Screw the regulator retaining bolts (1, 4) against the door while applying torque of 10 n.m (88 lb in). Next connect the electrical connector to the regulator motor, then take away the window support before guiding the window to touch the regulator guide. Attach the energy absorber to the door after you manually operate the window to the upper position until it stays in the channel and then install the energy absorber retainer components. Place the regulator bolt hole covers and water deflector along with the door trim panel.

Loosely tighten the regulator window carrier bolts, operate the window upward to ensure it remains in the run channels, and install the nut that retains the motor to the door, tightening it to 9 N.m (80 lb in).

Remove the nut securing the motor to the door.

Insert the regulator through the door opening in a semi-horizontal position, then position it fully forward into the door cavity before rotating it to a vertical position.

Remove the covers that hide the holes for the regulator bolts.

Remove the three window guide to regulator bolts and raise the window to the full up position for support.
