Step-by-step troubleshooting methods:

Check the fuse: Inspect the fuse for the power door locks. A blown fuse can prevent the system from functioning.
Test the key fob: If the key fob isn’t working, replace the battery and see if that resolves the issue.
Check the actuator: Listen for clicking sounds when the button is pressed. If there is no sound o r it’s very faint, the actuator might be faulty.
Inspect the wiring: Look for signs of loose o r damaged wiring. A break in the wiring can prevent the system from working.
Test the switch: Use a multimeter to check if the power door lock switch is sending power to the actuator.
