Lock, Rear Driver Side

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.

Remove the screws from the door lock and extract the door lock and cable through the access hole in the door inner panel, disconnecting the electrical connector from the lock.
