Solution

1. Preparation

Gather tools: multimeter, fuse puller, screwdrivers, and a flashlight.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Adjust Brightness Control

Locate the dashboard brightness control knob (usually found on the instrument panel).
Turn the knob to adjust the brightness to the desired level and check if the lights improve.

3. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or hood).
Identify the fuse related to the dashboard lights using the diagram on the fuse box cover.
Remove the fuse using a fuse puller and inspect it for continuity.
- If blown: Replace with the same amperage fuse (typically 10A or 15A depending on the model).

4. Check Battery Voltage

Reconnect the negative battery terminal.
Use a multimeter to measure the battery voltage while the engine is off.
- If the voltage is low: Recharge or replace the battery as needed.

5. Inspect Wiring

Remove the dashboard cover using a screwdriver.
Visually inspect wiring and connectors for any signs of wear, corrosion, or loose connections.
Repair or replace damaged wiring as necessary.
