Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, socket set, and electrical tape.
Disconnect the battery to ensure safety while working on electrical systems.

2. Inspect and Clean Fuse Box

Remove the fuse panel cover.
Visually inspect each fuse for signs of damage.
Clean any corrosion using an electrical contact cleaner.

3. Check and Repair Wiring

Inspect wiring harnesses connected to the affected circuits.
Look for any signs of wear or damage; repair or replace damaged sections using solder and heat shrink tubing.
Ensure all connectors are clean and securely attached.

4. Test Electrical Components

Disconnect components powered by the blown fuse one at a time (e.g., lights, radio).
Use a multimeter to test for shorts; if a component is faulty, replace it.

5. Reconnect Battery and Test

Reconnect the battery.
Replace the blown fuse with a new one of the correct amperage.
Start the vehicle and test the affected electrical systems.
