Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, fuse puller, screwdriver set, and wire connectors.
Ensure the vehicle is parked safely and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Fuses

Locate the fuse box according to the owner's manual.
Use a fuse puller to remove the power lock fuse.
Inspect the fuse for continuity using a multimeter; replace if blown with the same amperage rating.
Reinstall the fuse and reconnect the battery.

3. Inspect and Repair Wiring

Remove the door panel using a screwdriver and gently detach clips.
Visually inspect the wiring harness for any signs of wear or damage.
Repair or replace damaged wires or connectors as necessary, using wire connectors for secure connections.

4. Test and Replace Door Lock Actuators

With the door panel removed, access the door lock actuator.
Disconnect the actuator and apply battery voltage directly to it to check for movement.
If the actuator does not respond, replace it with a new unit following manufacturer specifications.

5. Reassemble and Test

Reattach the door panel ensuring all clips are secured.
Reconnect the battery and perform a test of the power locks using the key fob and interior switch.
Verify that all doors lock and unlock properly.
