3. Check Fuses

Open the fuse box (typically located under the dashboard or in the engine compartment).
Locate the fuse designated for the instrument panel lighting (refer to the owner's manual).
Visually inspect the fuse; if blown, replace it with a fuse of the same amperage.

4. Remove Instrument Cluster

Use a screwdriver to remove any screws securing the instrument cluster.
Carefully pull the cluster away from the dashboard.

5. Inspect and Replace Bulbs

Remove the bulbs from their sockets by twisting them counterclockwise.
Inspect bulbs for any signs of burning or damage. Replace any faulty bulbs with new ones of the same type.

6. Reassemble and Test
