🔧 Altima - Rear Door Lock Actuator Replacement

To replace the rear door lock actuator on your Altima, the exact procedure and the correct part depend on which rear door (left or right) you’re working on, and the inside door panel setup (power vs manual window/lock hardware). Once I have that, I’ll lay out the exact step-by-step with the correct fasteners and torque specs.

⚠️ Safety & Precautions

• ⚠️ Keep the key out of the ignition and windows fully up before starting.
• ⚠️ If your Altima has side airbags in the door, disconnect the battery and wait 3 minutes before unplugging any door connectors.
