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

  A: The replacement of the front door Window Regulator starts by taking out both the front door trim panel and the front door water deflector. When removing window regulators the door should be stabilized by using cloth-backed body tape placed from the window across the top edge of the door opening. Mark the spring with a marker or grease pencil while also disconnecting the wiring harness from the regulator motor. This will help during re-installation. The door module coil spring tool (J 38864) enables spring tension release allowing removal of the power Window Motor from the lock module and regulator uninstallation. The installation process requires users to position the regulator on the lock module, apply lubrication to the motor drive gear and regulator sector teeth before reattaching the power Window Motor to the lock module with correct counterbalance spring tension specified by the marked line. After using the door module coil spring tool (J 38864) to adjust spring tension, reattach the wiring harness to the regulator motor before placing on the front door water deflector and front door trim panel.
