Solution

1. Preparation

Gather tools and necessary parts.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Check Dimmer Switch

Locate the dimmer switch on the dashboard.
Rotate the dimmer switch to the maximum setting to ensure it is not the issue.

3. Inspect and Replace Fuse

Locate the fuse panel (usually under the dashboard or in the engine compartment).
Identify the dashboard light fuse using the panel diagram.
Remove the fuse using a fuse puller and inspect it for any signs of damage or burning.
If blown, replace it with a fuse of the same amperage rating (refer to the vehicle manual).

4. Inspect Wiring Harness

Remove the dashboard cluster cover using a screwdriver to access the wiring.
Carefully inspect the wiring harness for any frayed wires or loose connections.
If any damage is found, repair or replace the affected wiring.

5. Test Dashboard Light Voltage

Reconnect the battery.
Use a multimeter to check voltage at the dashboard light connector.
If no voltage is present, trace the wiring back to find the source of the issue or check the dashboard cluster itself.
