Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and trim removal tools.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Using the fuse puller, check the fuses related to the door locks (refer to owner's manual for specific fuse locations).
Replace any blown fuses with the same amperage rating.

3. Test and Replace the Power Door Lock Switch

Remove the driver's door panel using a screwdriver and trim removal tools.
Disconnect the electrical connector from the power door lock switch.
Use a multimeter to test for continuity across the switch terminals when the button is pressed.
If the switch is faulty, replace it with a new one by reversing the removal process.

4. Inspect the Door Lock Actuators

While the door panel is removed, visually inspect the door lock actuators for any signs of damage or disconnection.
Check the wiring harness for loose connections or corrosion.
If an actuator is faulty, remove the screws securing it and replace it with a new actuator.

5. Reassemble and Test

Reattach the door panel carefully, ensuring all clips are secured.
Reconnect the vehicle's battery.
Test the key fob and door lock switch to confirm functionality.
