2. Inspect Fuses

Locate the fuse box under the driver's side dashboard.
Remove the cover and identify the fuse for the dashboard lights (refer to the fuse diagram).
Use a multimeter or a fuse tester to check if the fuse is blown.
Replace the blown fuse with one of the same amperage rating.

3. Check Dimmer Switch

Locate the dimmer switch, typically found on the dashboard near the headlight switch.
Adjust the dimmer switch to different positions to see if any illumination occurs.
If no change is observed, consider replacing the dimmer switch.

4. Test Dashboard Light Bulbs

Remove the instrument cluster by unscrewing the retaining screws and gently pulling it out.
Disconnect the wiring harness from the back of the cluster.
Remove the light bulbs from their sockets and test each bulb for continuity using a multimeter.
Replace any burnt-out bulbs with new ones.

5. Inspect Wiring and Connectors

Inspect the wiring harness for any signs of wear, fraying, or corrosion.
Ensure all connectors are securely attached and free of corrosion.
Repair or replace any damaged wiring or connectors.
