Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface with the engine off.
Tools Required:
- Multimeter
- OBD-II scanner
- Socket set
- Screwdrivers
- Pliers
- Electrical tape
- Wire connectors

2. Inspect and Replace Blown Fuses

Open the fuse box and identify any blown fuses using the fuse diagram.
Remove and replace any blown fuses with fuses of the same amperage.
Safety Warning: Ensure the vehicle is off before working on electrical components.

3. Check and Repair Wiring

Inspect the wiring harness for frayed wires or loose connections.
If damaged, cut the affected section and splice in new wire using appropriate gauge wire.
Use electrical tape to insulate and protect the repaired area.
Ensure all connections are secure and free from corrosion.

4. Test Electrical Components

Reconnect any disconnected components one at a time and test their functionality.
Use a multimeter to check for proper voltage at the connectors of each component.
If a component fails, replace it with a new one.

5. Verify Ground Connections

Locate ground points throughout the vehicle and ensure they are clean and tight.
Remove any rust or corrosion, then reconnect securely.
