Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Check the Dimmer Switch

Locate the dimmer switch on the dashboard.
Turn the dimmer switch to the maximum setting and observe if the lights activate.
If the lights work, the issue was with the dimmer settings. If not, proceed to the next step.

3. Inspect and Replace the Fuse

Locate the fuse box under the dashboard or the engine compartment.
Refer to the fuse diagram in the owner’s manual to identify the dashboard light fuse.
Remove the fuse using a fuse puller or pliers and inspect it for a break.
If the fuse is blown, replace it with a fuse of the same amperage rating (typically 7.5A or 10A).

4. Check Wiring Connections

Inspect the wiring harness connected to the dashboard.
Disconnect the harness and check for any loose wires, corrosion, or damage.
Reconnect the harness securely and ensure all connections are tight.

5. Test the Dashboard Light Bulbs

Remove the dashboard cover as per the service manual instructions.
Carefully take out the dashboard light bulbs from their sockets.
Use a multimeter to test each bulb for continuity.
Replace any burnt-out bulbs with new ones of the same specifications.

6. Reassemble and Test

Reassemble the dashboard components and ensure all screws are tightened.
Reconnect the negative battery terminal.
Start the vehicle and check if the dashboard lights illuminate properly.
