Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative terminal of the battery for safety.

2. Check and Replace Fuses

Locate the dashboard fuse using the owner's manual.
Remove the fuse with a fuse puller or needle-nose pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.
Reconnect the battery terminal and test the dashboard display.

3. Inspect Wiring Harness

Remove the dashboard panel to access the wiring harness.
Check for loose connections or frayed wires in the harness.
Secure any loose connections and repair any damaged wires using electrical tape or heat shrink tubing.
Reassemble the dashboard panel and reconnect the battery.

4. Reset Electrical System

With the negative battery terminal still disconnected, wait for about 10-15 minutes.
Reconnect the negative terminal securely.
Start the vehicle and check if the dashboard display is operational.

5. Replace Instrument Cluster (if necessary)

If the display remains non-functional after the above steps, consider replacing the instrument cluster.
Remove the dashboard cover and unscrew the instrument cluster mounting screws.
Disconnect the wiring harness from the back of the cluster.
Install the new instrument cluster by reversing the removal process.
