Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shock and further damage.

2. Inspect and Replace Blown Fuses

Remove the blown fuse using a fuse puller or needle-nose pliers.
Replace it with a fuse of the same amperage rating.
Reconnect the battery and test if the new fuse blows again.

3. Repair Wiring Issues

If damaged wiring is found, cut the damaged section and strip the ends of the wires.
Use solder or wire connectors to splice the wires together securely.
Wrap the repaired area with electrical tape or heat shrink tubing to insulate.

4. Clean and Secure Connectors

Disconnect the light fixtures and inspect for moisture or corrosion.
Clean connectors using electronic cleaner spray and a brush.
Ensure that all connections are tight and secure before reassembling.

5. Test Interior Lights

Reconnect the battery.
Turn on the interior lights and observe if the issue persists.
If the lights function correctly, reinstall any removed panels or components.
