How to replace the front side Door Latch Assembly on Buick Rainier?

The first step to changing the front side door latch consists of closing the entire window completely. Separate the door trim panel along with the rear section of water deflector. Disconnect the retaining clip of the lock rod from the outside Door Handle and remove the rod from the hook. Begin by unfastening the lock cylinder rod from its position at the cylinder if you have this equipment installed and remove the interior Door Handle. Remove the 3 screws (Part Number: 123456) holding the latch to the door structure. The electrical connectors may need removing from the latch before you remove it from the door. Record the position of both inside and outside handle lock rods before removing them from the latch followed by the actuator. The installation process requires attaching the actuator to the latch followed by installation of the inside and outside handle lock rods according to their noted positions. The door accepts the latch when you position it correctly for electrical connector assembly before reattaching it. Screw in the three parts numbered 123456 to the latch while tightening them to 10 n.m or 89 lb in torque. The installation process requires reattachment of the inside Door Handle while locking the lock cylinder rod to the cylinder when equipped and installing the outside Door Handle lock rod which requires retention with its specific lock rod retaining clip. The process ends with reinstalling both components together: the water deflector along with the door trim panel.

How to replace the front side Door Latch Assembly on Buick LeSabre?

The first step for front side door latch replacement includes placing the window at full up and removing door trim panel, door module, inside Door Handle and water deflector. To access the electrical cables the lock rod as well as the outside Door Handle rod requires the opening of a clip. Begin by removing the door latch fasteners followed by the window run channel fastener and position the window run channel to the side. The door latch removal procedure includes extracting the inside Door Handle and lock rods attached to the door latch after which the handle and rods need to be detached from the door latch. Putting the door latch together with attached inside Door Handle and lock rods requires following the fastener notice in service precautions then installing the door latch into the door. Attach the door latch fasteners up to 10 n.m (89 lb in) while inserting the outside Door Handle rod into the latch clip and pushing the clip shut. The lock cylinder rod needs to be installed inside the door latch after which the window run channel fastener requires a tightening torque of 9 n.m (80 lb in). The inside Door Handle needs to be reinstalled followed by electrical connector wiring before checking Door Handle and lock cylinder function which serves as a prerequisite for door trim panel and water deflector installation. Installation of the water deflector must be followed by the door module placement and then the door trim panel.
