Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Check and Adjust Dimmer Switch

Locate the dashboard light dimmer control, usually on the left side of the dashboard.
Rotate the dimmer control to see if the lights adjust. If they do not, proceed to the next step.

3. Inspect and Replace Fuses

Access the fuse box; refer to the owner's manual for the exact location and diagram.
Identify the fuse for the dashboard lights, typically labeled as "Instrument" or "Cluster."
Remove the fuse using a fuse puller and inspect it visually. If blown, replace it with a new fuse of the same amperage (usually 10A or 15A).

4. Test Instrument Cluster Power Supply

Reconnect the battery terminal.
Use a multimeter to test the power supply at the instrument cluster connector.
Ensure there is a voltage reading (typically around 12V). If not, trace back the wiring for continuity.

5. Inspect Wiring Connections

If the power supply is present, disconnect the instrument cluster connector and visually inspect for damage or corrosion.
Clean contacts with electronic cleaner if necessary and reconnect.
If damaged, replace the wiring harness or connector as needed.
