Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the fuse for the dashboard lights (refer to the owner's manual for specific fuse location).
Check the fuse visually or use a multimeter to test continuity.
If blown, replace with a new fuse of the same amperage.

3. Check and Replace Bulbs

Remove the instrument cluster by unscrewing any visible screws and gently pulling it out.
Inspect each bulb socket for signs of wear or burnt-out bulbs.
Replace any burnt-out bulbs with new ones that match the specifications (usually T10 or T5 type bulbs).

4. Inspect Wiring and Connectors

Examine the wiring harness connected to the instrument cluster for any frays, cuts, or corrosion.
Ensure all connectors are securely fastened and not corroded. Clean any corroded terminals with electrical cleaner.

5. Reassemble and Test

Reinstall the instrument cluster by reversing the removal steps.
Reconnect the negative battery terminal.
Turn on the ignition and check if the dashboard lights are functioning.
