Solution

1. Preparation

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

2. Check Dimmer Switch

Locate the dashboard dimmer switch, typically found near the headlight switch.
Rotate the dimmer switch back and forth to ensure it’s functioning correctly.
If this resolves the issue, reconnect the battery and test again.

3. Inspect and Replace Fuse

Access the fuse box; refer to the owner's manual for the specific fuse related to the dashboard lights.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for signs of damage; replace if blown with an identical amperage fuse.

4. Test Dashboard Light Connectors

Reconnect the battery temporarily.
Use a multimeter to check for voltage at the dashboard light connectors with the vehicle in the "ON" position.
If no voltage is present, trace back to the dimmer switch and wiring.

5. Repair or Replace Wiring

Visually inspect wiring for any signs of wear or damage.
If damaged, repair the wiring with appropriate connectors and electrical tape.
Reconnect everything and retest the dashboard lights.
