How to replace the rear Door Latch Assembly on Buick LaCrosse?

The process to change the rear Door Lock starts with the removal of rear door trim panel and rear door water deflector. Notice that outside handle lock rods on the outside handles need adjustment before operation by eliminating all free play between handles and locks. Open the outside handle rod to the lock clip before releasing the rod from the Door Lock. Extract the lock and cable/rod from the door after taking out screws (1, 3, 2) which keep the lock attached to the door by working through the access hole in the door inner panel. Use the provided tab on the electrical connector todetach it from the lock system then extract the Door Lock assembly together with its cable. Installation requires you to connect the Door Lock with cable to the lock and to reconnect the electrical connector through tab pushing then insert the lock and cable/rod through the door panel access hole inside the door. First secure the Door Lock with screws (1, 3, 2) starting with the top screw followed by the bottom screw and ending with the middle screw when securing. Tighten all screws to 10 n.m (89 lb in). Seam the outside handle rod through the clip while pulling the clip sides together. Check the door function before implementing the rear door water deflector and rear door trim panel reinstall.

How to replace the front Door Latch Assembly on Buick LaCrosse?

The procedure for front Door Lock replacement starts with removing both the front door trim panel and the front door water deflector. The outside handles utilize adjustable outside handle lock rods yet the installation process needs every lock rod to be completely free from the outside handle before operation. Open the outside handle rod to break the lock clip on the Door Lock while keeping all outside handle rods separate from the lock. Test the outside Door Handle after removing its lock cylinder rod because replacement will be necessary when you find any mismatch between components. After unscrewing the Door Lock you should extract the Door Lock and cable through the access hole in the door inner panel by disconnecting the electrical connector from the lock. Set the lock and cable into position in the door before reattaching the electric connector and threading them through the access hole. Fasten the Door Lock screws which need to be tightened to 10 n.m (89 lb in) before connecting the lock cylinder rod to the outside Door Handle. Shift the outer handle rod through the door clip until it is secured by closing the clip around the rod. The procedure ends by putting back the inside Door Handle while conducting a check for door functionality and finally attaching the front door water deflector and front door trim panel.
