Safety Warnings:
- Disconnect the battery before working on electrical systems to avoid shorts.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the cover and locate the radio fuse.
Use a fuse puller or pliers to extract the fuse.
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage (usually 10A or 15A).
Reinstall the fuse and cover.

3. Inspect Wiring and Connector

Remove the radio unit from the dashboard using a socket set and flathead screwdriver.
Carefully detach the radio harness connector and inspect for corrosion, damage, or loose connections.
If any issues are found, repair or replace the affected wiring.
Reconnect the harness securely before reinstalling the radio.

4. Verify Battery Voltage

Check the vehicle's battery voltage using a multimeter; it should read approximately 12.6 volts or higher.
If the battery voltage is low, charge the battery or replace it if necessary.

5. Reinstall Radio and Test
