Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Disconnect the negative battery terminal to avoid electrical shock.

2. Inspect and Replace Fuses

Locate the interior fuse box, usually under the dashboard or near the driver's side.
Identify the specific fuses for power windows and locks using the fuse diagram.
Pull each fuse out and visually inspect for signs of damage or use a multimeter to test continuity.
Replace any blown fuses with new ones of the same amperage rating.

3. Check Wiring and Switches

Remove the door panel to gain access to the wiring harness and switches.
Inspect the wiring for any signs of wear, fraying, or corrosion.
Disconnect the window and lock switches and test them for continuity with a multimeter.
If faulty, replace the switches with new ones.

4. Reconnect and Test

Reconnect any disconnected electrical connectors.
Reattach the door panel securely.
Reconnect the negative battery terminal.
Test the power windows and locks to ensure they function properly.
