🔧 3500 - Front Door Lock Actuator Replacement

On your 3500, the “door lock actuator” is typically serviced as part of the door latch/lock assembly inside the door. The trim panel has to come off, then the latch/actuator is removed from the door edge and swapped over.

⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before unplugging door wiring so you don’t set faults or short anything.
• ⚠️ Support the door glass if you loosen/move the window regulator for access.
• ⚠️ Use plastic trim tools to avoid breaking clips and cracking the panel.
