Solution

1. Preparation

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

2. Inspect and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use the fuse puller tool to carefully remove the relevant fuse for the dashboard lights.
Check the fuse for continuity. If blown, replace with a new fuse of the same amperage (refer to the owner's manual for specifications).

3. Test the Dimmer Switch

Locate the dashboard dimmer switch, usually positioned near the headlight switch.
Turn the dimmer switch from the lowest to the highest setting while observing the dashboard lights.
If the lights do not respond, consider replacing the dimmer switch.

4. Inspect Dashboard Wiring

Remove the dashboard cover by unscrewing and unclipping it gently.
Inspect all wiring harnesses connected to the instrument cluster for loose connections or signs of damage.
If any connectors are corroded, clean them with electrical contact cleaner or replace damaged wiring.

5. Replace Dashboard Light Bulbs

If the bulbs are found to be faulty during testing, remove the instrument cluster from the dashboard.
Carefully detach the cluster from its connectors.
Replace any burnt-out bulbs with new ones that meet the specifications (check the owner's manual for bulb type).
Reassemble the instrument cluster and dashboard cover.
