Solution

1. Preparation

Gather tools: screwdriver set, multimeter, OBD-II scanner, and replacement bulbs (if necessary).
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the fuse for the dashboard lights using the diagram.
Use a multimeter to check the fuse for continuity. If blown, replace it with a fuse of the same amperage.

3. Replace Dashboard Light Bulbs

Remove the instrument cluster cover using the screwdriver.
Carefully detach the instrument cluster by unscrewing and disconnecting any electrical connectors.
Test each bulb socket with a multimeter to confirm functionality. Replace any burned-out bulbs with new ones.
Reassemble the instrument cluster and reconnect the connectors.

4. Inspect Wiring and Connectors

With the instrument cluster removed, visually inspect all wiring and connectors for fraying, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors as necessary.

5. Reconnect Battery and Test

Reconnect the vehicle battery.
Test the dashboard lights by turning on the ignition and adjusting the dimmer switch to verify functionality.
