GM 13533615 Latch Assembly, Front S/D

To remove the door latch, start by removing the door trim panel and water shield. Then, remove the retainers for the cable and disconnect the electrical connector from the latch. Detach the rods from the latch and remove the latch mounting fasteners. For installation, simply reverse the removal process. To remove the outside handle, open the door and remove the small access cover. Loosen the retainer but do not remove it. Pull the door handle out halfway and remove the small cover, then remove the handle. Installation is the reverse of removal. To remove the door lock cylinder, remove the door trim panel and plastic water shield. Remove the door handle and disconnect the latch rod from the lock cylinder and handle rod. Remove the fastener securing the door handle housing and release the retainer from the rear of the door lock cylinder. Push the lockout of the housing. Installation is the reverse of removal.

Troubleshooting involves checking circuit protection (fuses and circuit breakers), verifying voltage at the switches, checking for continuity, inspecting wiring between components, and testing solenoids for voltage and ground. If issues persist, retrieve trouble codes from the BCM using a scan tool.
