Window Regulator, Front Passenger Side

One must start by supporting the window glass and raising it before taking out the trim panel and water deflector. Detach the two bolts which hold the window to the regulator and then unfasten the bolts from the window regulator. Disassemble the door window regulator by folding its opposite sides so that it can be completely extracted from the door framework. Place the regulator inside the door structure to install it while applying a slight twisting motion to achieve proper seat between the components. Before tightening the regulator bolt threads you must first spread Permatex Threadlocker (Part Number 24200, GM P/N 12345382). Fasten the window regulator bolts then tighten them at 9 N.m (80 lb in). Place the window glass on the regulator before tightening the bolts which will secure the window regulator with the same torque value. The last step involves reinstallation of the water deflector along with the trim panel followed by window lowering until inspection of its functionality is completed.

The procedure to replace a front power Window Regulator starts by supporting the window glass while in an elevated position before removing the trim panel along with the water deflector. Begin by disconnecting the electric motor harness before removing the two bolts that secure the window glass to the regulator and subsequently the bolts from the Window Regulator. Pulling both sides of the Window Regulator assembly toward each other creates sufficient space to extract it from the door opening. Secure the regulator within the door structure by applying light twisting motion to achieve proper installation. Before tightening the regulator bolts apply permatex threadlocker (Part Number 24200, GM P/N 12345382) to their threads. First secure the bolts into position on the Window Regulator until torque reaches 9 n.m or 80 pound-inches. Synchronize the window glass with the regulator before applying the bolts that secure the window to its regulator position. Proceed by tightening the bolts to 9 n.m (80 lb in). After that reinstall both water deflector and trim panel before lowering the window and inspecting the windows operation.

Remove the bolts from the window regulator.

Install the new module and secure it with the retaining bolts.

Reinstall the speaker, water deflector, and door trim panel.

Remove the glass window to access the window motor retaining screws.

Remove the 3 bolts (W706202) from the front side of the motor.

Begin by installing the window regulator motor followed by the module into the door.

Wiggle the motor into place on the cable housing, then install the 3 bolts (W0133-1620630) to the window motor, tightening them to 5 N.m (44 lb in).

Reinstall the water deflector and the trim panel, then lower the window and inspect its operation.

Tighten them to 9 N.m (80 lb in).

The trim panel and the water deflector.

Take out the window regulator assembly by folding both sides together.

Slide the motor partially out of the gear/spool to allow finger access to the gear spool, then hold the gear/spool in the housing and remove the motor.

Detach the 2 bolts securing the window to the regulator.

First, raise and support the window glass.

Tighten them to 9 N.m (80 lb in).

Reinstall the water deflector and the trim panel, lower the window, and inspect its operation.

Reinstall the water deflector and the trim panel, then lower the window and inspect its operation.

Remove the trim panel and the water deflector.

Align the window glass to the regulator and install the bolts that hold the window to the regulator, also tightening them to 9 N.m (80 lb in).

By folding both sides together.
