Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and is powered off.
Disconnect the 12V battery to prevent electrical shock.

2. Battery Replacement (if necessary)

Remove Old Battery:
- Open the trunk and locate the battery compartment.
- Disconnect the negative terminal first, followed by the positive terminal.
- Remove any securing brackets and lift out the old battery.
Install New Battery:
- Place the new battery in the compartment.
- Secure it with brackets.
- Connect the positive terminal first, followed by the negative terminal.
- Ensure terminals are tight and corrosion-free.

3. Repair Wiring Connections

Inspect Wiring:
- Carefully inspect identified damaged wiring or connectors.
- Use wire strippers to remove insulation from damaged wires.
Splice Wires:
- Use heat-shrink connectors or solder to make repairs.
- Insulate with electrical tape after securing connections.
Reinstall Components:
- Reinstall any components removed during inspection.

4. Replace Fuses/Relays

Identify Faulty Components:
- Refer to the vehicle's manual to locate fuses/relays associated with the problematic systems.
Replace:
- Pull out the faulty fuses using a fuse puller.
- Insert new fuses or relays ensuring they match specifications.

5. Ground Connection Repair

Inspect Ground Points:
- Locate ground points in the vehicle's electrical system, usually near the battery and chassis.
Clean and Secure:
- Clean any corrosion using a wire brush.
- Tighten ground connections to ensure a solid electrical path.
