Sub-steps:
1. Locate the fuse box (usually under the dashboard or in the engine compartment).
2. Identify and remove any blown fuses using a fuse puller or pliers.
3. Replace blown fuses with ones of the same amperage rating.
4. Recheck the dashboard lights to see if the issue persists.

4. Inspect Wiring and Connectors

Sub-steps:
1. Remove any plastic covers or panels to gain access to wiring behind the dashboard.
2. Visually inspect all electrical connectors for looseness or corrosion.
3. Repair or replace damaged wires and connectors as necessary.
4. Secure any loose connections to ensure a solid electrical connection.

5. Test Ignition Switch

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
