Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and Phillips screwdriver.
Disconnect the negative battery terminal to prevent electrical shorts and ensure safety.

2. Check and Replace Key Fob Battery

Open the key fob using a flathead screwdriver.
Remove the old battery and replace it with a new CR2032 battery, ensuring correct polarity.
Reassemble the key fob and test the door locks.

3. Inspect and Replace Fuses

Locate the fuse box under the dashboard or in the engine compartment.
Identify the fuse linked to the power door locks (consult the owner's manual for specifics).
Remove the fuse with a fuse puller or pliers and inspect it. Replace if blown, using the same amperage rating.

4. Repair Wiring and Connectors

Remove the door panel using a socket set and screwdriver.
Inspect the wiring harness connected to the door lock actuator for any signs of wear, fraying, or corrosion.
Repair or replace damaged wires and ensure all connectors are securely attached.

5. Test and Replace Door Lock Actuators

Use a multimeter to test the voltage at the door lock actuator connector when the lock switch is activated.
If no voltage is present, trace back to the door lock switch for further testing.
If voltage is present but the actuator does not function, replace the actuator by:
- Removing the screws securing it to the door.
- Disconnecting the actuator wiring harness.
- Installing the new actuator and securing it with screws.

6. Reassemble Components

Reinstall the door panel securely using the original screws.
Reconnect the negative battery terminal.
Test the power door locks with the key fob and door switches.
