Solution

1. Preparation

Gather tools and components.
Disconnect the battery to prevent electrical shock and further damage.
Tools Required: Multimeter, socket set, screwdrivers, wire stripper/crimper.

2. Inspect and Repair Wiring

Inspect Wiring:
- Check all wiring connected to blown fuses.
- Look for frayed wires or exposed conductors.
Repair Damaged Wires:
- Cut out damaged sections using wire cutters.
- Strip the ends of the wires to expose fresh copper.
- Use wire connectors or solder to join wires, ensuring proper insulation.

3. Replace Fuses

Remove Blown Fuses:
- Use a fuse puller or pliers to carefully remove the blown fuses.
Install New Fuses:
- Replace with fuses of the same amperage rating as specified in the fuse box cover.

4. Check Ground Connections

Inspect Ground Points:
- Locate ground connections in the affected circuits.
- Clean any corrosion using a wire brush and re-tighten the connections.

5. Reconnect Battery and Test

Reconnect the battery.
Turn on the vehicle and test all electrical components associated with the replaced fuses to ensure functionality.
