Window Regulator, Front Driver Side

Beginning the front side door Window Regulator replacement for sedans and wagons requires first opening the window to maximum height then removing the door trim panel. You must then remove the water deflector before taping the window to remain at full up. The door trim panel wiring harness connection occurs after you use the inner door panel access holes to loosen the window clamp fasteners by 4 revolutions. Betray the Window Regulator until it rests at 3/4 of its total range and then remove the electrical connector from the motor. Remove fasteners 1, 2, 3, 4, 5 to extract the Window Regulator from the door opening. Before installing the Window Regulator take it into the door panel while maintaining fastener safety instructions. Secure the Window Regulator fasteners (1, 2, 3, 4, 5) by torquing them to 9 nm (80 lb in). Lower the window using the tape until glass reaches its maximum rearward point inside the window channel. Start the vehicle while connecting the power Window Motor electrical connector to obtain peak power that helps the Window Motor position itself correctly. Raising the window to its maximum height enables you to tighten the window clamp fasteners to 11 nm (98 lb in). Drive the vehicle while verifying proper operation and tight sealing of the window before turning off the engine. The installation concludes by fitting the water deflector along with the door trim panel.

Raise the window to the full up position and tighten the window clamp nuts to 11 Nm (95 lb in).

Place the window regulator into the door and install the window regulator bolts (1, 2, 3, 4, 5), tightening them to 9 N.m (80 lb in).
