GM 20995846 Front Side Door Lock (W/O Handle)

For 2007 and earlier models, start by raising the window fully, then remove the door trim panel and watershield. Next, take out the anti-theft shield fasteners from the door jamb, remove the push-pin for the door handle fastener, and take out the shield if present. Pry open the plastic clip for the lock cylinder rod-to-door latch and handle rod, disconnect the rods from the latch assembly, and then remove the watershield and door handle nuts to take out the handle and rods from outside the door, with installation being the reverse of removal. For 2008 and later models, this procedure pertains only to the outside door handle lever; if replacing the handle reinforcement and lock, remove it along with the door latch as a single assembly. Start by removing the trim cap for the outside handle retaining screw and the screw itself, then take off the watershield and the cover from the outside handle. To remove the handle, pull it out of the door and to the rear to disengage it from the handle reinforcement, and inspect the outside door handle seals for any damage, replacing them if necessary, with installation being the reverse of removal. For the inside door handle on 2007 and earlier models, remove the door trim panel, then the retaining bolt to detach the handle assembly, disconnect the actuator rod, and remove the handle, with installation being the reverse of removal. For 2008 and later models, remove the door trim panel, disconnect the actuator cable from the inside door handle, and then remove the handle from the door panel, with installation being the reverse of removal. For the door latch or outside door handle reinforcement on 2008 and later models, first remove the outside door handle lever, then the door trim panel. Remove the trim cap for the outside door handle reinforcement retaining screw and the screw itself, followed by the exterior retaining screw for the reinforcement. Take out the latch mounting fasteners, pull out the latch and rods as a single assembly, disconnect the rods and electrical connector from the latch, and disconnect the inside door handle actuator cable. Place the latch and outside door handle reinforcement on a clean workbench, disconnect the actuator rods from the latch or outside door handle reinforcement, and installation is the reverse of removal. For the door lock cylinder, on 2007 and earlier models, remove the door latch and outside door handle, while for 2008 and later models, remove the door latch and outside door handle reinforcement. Then, remove the E-clip and rod arm from the lock cylinder, press the release button, and take out the lock cylinder. When installing, push the lock cylinder all the way into the outside door handle reinforcement until it clicks into place, with installation otherwise being the reverse of removal.
