2. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the audio system fuse (refer to the owner’s manual for the specific fuse number).
Use a multimeter to check for continuity in the fuse.
- If the fuse is blown:
  - Replace it with a new fuse of the same amperage (e.g., 15A).

3. Inspect Wiring and Connections

Remove the head unit from the dashboard using a trim removal tool.
Check all wiring connections to ensure they are secure and undamaged.
Inspect the speaker wires running to each speaker for any signs of wear or disconnection.
If damaged, repair or replace the wiring as necessary.

4. Test the Head Unit

Reconnect the battery terminal.
Power on the audio system and test all audio sources (radio, Bluetooth, auxiliary).
If sound is still absent, consider replacing the head unit with a compatible replacement part.

5. Final Assembly

After completing repairs or replacements, reassemble the head unit and dashboard components.
Ensure all connections are tight and secured.
