Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Wear safety glasses and gloves.

2. Inspect and Repair Wiring

Open the fuse box and remove any damaged fuses.
Tools Required: Screwdrivers, wire cutters, electrical tape, multimeter.
Check wiring insulation for breaks or abrasions, especially near the fuse box and component connections.
Repair any damaged wiring by cutting out the damaged section and splicing in new wire of the same gauge.
Use electrical tape to properly insulate any splices made.

3. Test Components

Reconnect the battery terminal.
Tools Required: Multimeter.
Check all components on the affected circuits (lights, window motors, etc.) using the multimeter to ensure they are functioning correctly.
Replace any faulty components as necessary.

4. Finalize Repairs

Replace any blown fuses with the correct amperage rating.
Safety Warning: Ensure no wires are pinched or exposed before reassembly.
Close the fuse box securely.
