🔧 Rear Door Lock Actuator - Replacement

Replacing the rear door lock actuator restores normal locking and unlocking if the door clicks, sticks, or only works intermittently. On your Ram, the actuator is built into the latch assembly, so the job involves removing the rear door trim panel, disconnecting the latch, and installing the new unit.

Difficulty Level: Intermediate | Estimated Time: 1.5-2.5 hours

Step 1: Remove the door trim screws

• Use the 7mm socket and Torx T20 screwdriver to remove the visible screws around the rear door panel.

Step 3: Remove the vapor barrier

• Use the flat-blade trim tool to carefully peel back the vapor barrier.
