Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal using a socket set to prevent electrical shock.

2. Inspect and Clean Battery Connections

Remove the positive terminal first, followed by the negative terminal.
Clean the terminals and cable ends with a wire brush to remove any corrosion.
Reconnect the positive terminal first, then the negative terminal and ensure they are tight.

3. Replace Fuse

Locate the fuse box, usually found in the glove compartment or under the hood.
Identify the specific fuse for the dashboard (refer to the owner's manual for the exact location).
Remove the faulty fuse using fuse puller or needle-nose pliers.
Insert a new fuse of the same amperage into the slot.

4. Inspect Wiring

Visual inspection of the wiring harness connected to the dashboard; look for frays, breaks, or loose connections.
If any wiring damage is found, repair or replace the affected wiring using appropriate gauge wire.
Ensure all connectors are properly seated and locked in place.

5. Reconnect Battery and Test

Reconnect the negative battery terminal first, then the positive terminal.
Turn on the ignition to check if the dashboard lights illuminate and the instrument cluster functions correctly.
