Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wire brush, electrical tape.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Fuse Box

Remove the fuse box cover.
Use a wire brush to clean any corrosion present on the terminals.
Inspect for damaged fuses and replace them if necessary.

3. Test and Repair Wiring

Check wiring harnesses visually and with a multimeter.
If damaged wiring is found, repair by splicing in new wire (use heat-shrink tubing for insulation).
Ensure all connections are secure and insulated.

4. Replace Faulty Components

If any electrical components (e.g., switches, motors) are found to be faulty, replace them with OEM parts.
Follow manufacturer specifications for installation and connection.

5. Reassemble and Test

Reinstall the fuse box cover and reconnect the negative battery terminal.
Replace any blown fuses with the correct amperage rating.
