The procedure for replacing escalade and pickup rear door locks starts by removing the trim panel together with the water deflector. The inside Door Handle and lock control rods should be detached first before removing the outside Door Handle using the correct method for crew cab vehicles by unsnapping the threaded clip and for 4-door yukon/tahoe vehicles by pushing in the clip. The power Door Lock connector gets disconnected first while you remove the lock assembly bolts which lets you extract the lock assembly from its vehicle position. Appearing on utility vehicles is an additional procedure to remove the child security lock from the lock assembly. To replace the lock assembly first place it into the vehicle before you install the child security lock if the vehicle is a utility model. The new lock assembly needs to be secured by bolts while power lock connector restoration follows. Follow these installation instructions to put back the outside Door Handle either by snapping the threaded clip used for crew cab vehicles or pushing in the clip used for 4-door yukon/tahoe vehicles. Install the water deflector then the trim panel as the final installation step.

To replace the Power Door Lock Actuator, one must collect the tools needed: Rivet Gun (J 34940). Start by detaching the trim panel, water deflector, and access hole cover if necessary. Then unplug the actuator lock control rod, and unplug the actuator wiring connector. Use a 3 mm (.125 in) drill bit to remove rivets and take out the actuator from the door. For installation, use Rivet gun ( J34940) and use the rivets to fix the new actuator on the door, followed by reconnection of actuator Lock control rod and attachment of the actuator wiring connector. Lastly, reattach the water deflector, trim panel, and access hole cover as needed.

The process to replace the rear side door lock actuator begins with raising the window followed by panel and water deflector removal. Detach both the inside door lock rod from its retention on the handle retainer clip as well as the manual door lock rod from its retention on door retainer clips. To detach the outside handle rod retainer use a screwdriver to remove the rubber plug along with the rod without disconnection. The door lock actuator should have its bolts removed to extract it along with control rods as one complete assembly. First disconnect the door lock actuator electrical connector then separate the control rods when equipment gives permission. First attach control rods to the assembly then connect electrical connectors to the door lock actuator if the system is equipped. After installing the door lock actuator to its position on the door structure you must connect the outside door handle control rod followed by attachment of the cylinder lock rod. Secure the door lock actuator using bolts that need to be tightened to 9 N.m (80 lb in). Link the door retainer clips together with the manual door lock and connect the inside door lock rod to handle retainer clip. Lastly you should install the water deflector and door trim panel while inspecting the operational function of all linked components.

The process for upper rear side door latch replacement starts with door trim panel removal then bolt removal followed by detachment of the latch rod to the latch. The next stage involves attaching the latch rod to the latch under the guidelines of Fastener Notice in Service Precautions. The upper rear side door latch requires installation onto the door before tightening bolts to a torque of 9 N.m (80 lb in). Reinstall both the door trim panel and the latch retaining bolts as the final step.

Start by removing the door trim panel before handling the water deflector together with the access hole cover for replacement of the rear door latch (Cargo Door Upper). First disconnect the control rod from its latch position and then uninstall the latch cover screw followed by the removal of the latch cover. The next procedure involves extracting the latch bolts before removing the latch from the door opening. Installation involves placing the latch onto the door but always follow the Fastener Notice in Service Precautions. Follow the Fastener Notice in Service Precautions by installing the latch bolts to 25 N.m tightness (18 lb ft) before attaching the control rod back to the latch. The door trim panel should be fixed last after covering and reinstalling the access hole for water deflectors if necessary.
