1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

Locate the fuse box, typically found under the dashboard on the driver’s side or in the engine compartment.
Use a fuse puller or pliers to remove the dashboard light fuse (check the owner's manual for the exact fuse number).
Inspect the fuse: if it appears broken or burned out, replace it with a new fuse of the same amperage.

3. Test and Replace Bulbs

Remove the dashboard panel using a trim removal tool to avoid damage.
Access the bulb sockets for the dashboard lights.
Remove the bulbs and visually inspect them for any signs of burning or damage; replace any faulty bulbs with new ones.

4. Check Wiring Connections

Inspect the wiring harness connected to the dashboard for any loose connections or frayed wires.
If any damages are present, repair or replace the wiring as necessary.

Reattach the dashboard panel securely.
Reconnect the negative terminal of the battery.
Test the dashboard lights by turning on the vehicle and checking the illumination of the dashboard.
