Here are the steps to follow:
1. Disconnect the battery: Disconnect the negative terminal of the battery to avoid any electrical accidents.
2. Locate the instrument cluster: The instrument cluster in a 1990 Nissan is located behind the steering wheel. Use the Phillips-head screwdriver to remove the screws that hold the instrument cluster in place, and then carefully remove it.
3. Identify the faulty wiring: Inspect the wiring of the instrument lights to identify any damage, loose connections, or burnt wires. Look for any signs of fraying, corrosion, or melting of the insulation.
4. Replace or repair the faulty wiring: If the wiring is damaged or broken, you will need to replace it. Use the wire cutters and strippers to remove the old wiring and connect the new wires using the electrical connectors. Make sure the connections are secure. If any of the wires are simply loose, reconnect them properly and wrap them with electrical tape for added security.
5. Solder the connections: After you have connected the new wires, use the soldering iron and solder to strengthen the connections. This will help ensure a reliable electrical connection.
6. Reinstall the instrument cluster: Once the wiring is repaired, carefully put the instrument cluster back in place and secure it with the screws.
7. Reconnect the battery: Reconnect the negative terminal of the battery to restore power to the instrument cluster.
8. Test the instrument lights: Turn on the ignition and check if the instrument lights are functioning properly. All of the lights should illuminate clearly.
Note: If you are uncomfortable working with electrical components, it is recommended to consult a professional automotive electrician for assistance.
