Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Inspect the Fuse Box

Tools Required: Screwdriver, flashlight
Remove the cover of the fuse box.
Visually inspect for any damaged fuses or signs of overheating.
Replace any blown fuses with new ones of the same amperage.

3. Check Wiring and Connections

Tools Required: Multimeter, wire brush
Disconnect the battery to prevent electrical shock.
Inspect wiring harnesses connected to the fuse box for frayed wires or shorts.
Clean any corroded ground connections using a wire brush and reconnect.

4. Test Electrical Components
