How to replace the front door window regulator on Buick Terraza?

The needed first step to change the front door Window Regulator involves taking off both the front door trim panel and the front door water deflector. Cloth-backed body tape should be placed on the window to secure it in position as the regulator is removed from the door. Wiring harnesses from the regulator motor should be disconnected while a reference line should be marked across the spring with a marker or grease pencil. The regulator spring tension can be released using the door module coil spring tool (J 38864). Next disconnect the power Window Motor from the lock module before removing the regulator. Connect the components by installing the regulator onto the lock module while applying lubrication between the motor drive gear and regulator sector teeth followed by proper alignment of the marked line during power Window Motor installation. The door module coil spring tool (J 38864) helps with spring tension installation during which you should reconnect the wiring harness to the regulator motor followed by reinstallation of the front door water deflector and trim panel.
