Solution

1. Preparation

Gather necessary tools and materials.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Access Fuse Box

Locate the fuse box, typically found under the dashboard or near the driver's side.
Use a screwdriver or a fuse puller to open the fuse box cover.

3. Inspect and Replace Fuse

Identify the correct fuse for the dashboard lights as per the owner’s manual.
Remove the fuse using a fuse puller or pliers.
- Tool Required: Fuse puller or needle-nose pliers
Inspect the fuse for a blown filament; if the metal strip inside the fuse is broken, the fuse is blown.
Replace the blown fuse with a new one of the same amperage (check the fuse rating on the fuse box cover).
- Parts Required: Replacement fuse (same amperage)

4. Reconnect Battery

Reconnect the negative terminal of the battery securely.
Ensure all connections are tight and free of corrosion.

5. Test Dashboard Lights

Start the vehicle and check if the dashboard lights are functioning correctly.
If flickering persists, further electrical diagnosis may be required.
