🔧 Rear Door Lock Actuator - Replacement

The rear door lock actuator is built into the latch assembly on your Ram, so this repair is usually done by removing the door trim panel, disconnecting the latch cables and wiring, then swapping the latch/actuator unit. A failing actuator can cause slow locking, no lock/unlock, or a door that won’t latch correctly.

Difficulty Level: Intermediate | Estimated Time: 1.5-3 hours

⚠️ Safety & Precautions

• Disconnect the negative battery cable before removing the door trim. The door contains electrical connectors and may have side airbag wiring.
• Wait at least 2 minutes after disconnecting the battery before unplugging door connectors.
• Support the door panel so you do not tear the wiring or break the clips.
• Do not force the latch rods or electrical plugs.
• If the window glass is loose or down, keep hands clear of the regulator track.
