Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box in the vehicle (usually under the dashboard or in the engine compartment).
Remove the fuse related to the power locks (refer to the owner's manual for the specific fuse location).
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.

3. Test and Replace Door Lock Switch

Remove the door panel using a socket set to access the door lock switch.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity when the switch is activated.
If the switch fails the test, replace it with a new one and reconnect it.

4. Inspect and Replace Door Lock Actuator

With the door panel still removed, locate the door lock actuator.
Disconnect the electrical connector and remove the actuator from the door.
Test the actuator by applying power directly to it; if it does not function, replace it.
Install the new actuator, reconnect the electrical connector, and reassemble the door panel.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Test the power locks using both the remote and the door switch to ensure proper function.
