Locate the fuse box, typically under the dashboard or in the engine compartment.
Use a fuse puller or needle-nose pliers to remove the audio-related fuses.
Inspect the fuses visually and check with a multimeter for continuity.
- If a fuse is blown, replace it with one of the same amperage.
Reinstall the fuses securely and recheck the audio system.

3. Check and Reconnect Infotainment Connections

Remove the trim panel surrounding the infotainment unit using a trim removal tool.
Unscrew the infotainment unit from the dashboard (typically requires a Torx or Phillips screwdriver).
Gently pull the unit out and inspect the wiring harnesses for secure connections.
- Reconnect any loose connectors.
Push the unit back into place and secure it with screws.

4. Test Audio System

Reconnect the negative battery terminal.
Start the vehicle and test the audio system across all functions (radio, Bluetooth, USB).
Adjust the volume and check if sound output is restored.
