Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the negative terminal of the battery to ensure safety.

2. Check the Dimmer Switch

Locate the dimmer switch on the dashboard, usually found near the headlight switch.
Rotate the dimmer switch to the maximum setting and check if the dashboard lights illuminate.

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the specific fuse for the dashboard lights (refer to the owner's manual for fuse diagram).
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace it if it is blown (use a fuse of the same amperage).

4. Inspect Wiring and Connectors

Access the back of the dashboard by removing any necessary trim panels (usually requires a flathead screwdriver or trim removal tool).
Visually inspect the wiring and connectors behind the dashboard for any signs of wear, corrosion, or damage.
Reconnect any loose connectors securely.
