Solution

1. Preparation

Gather necessary tools and parts.
Tools required:
- OBD-II scanner
- Multimeter
- Screwdriver set
- Trim removal tool
Safety warning: Disconnect the battery before working on electrical components to prevent shorts or shocks.

2. Check Audio Settings

Turn on the vehicle and the audio system.
Navigate to the audio settings on the head unit.
Ensure that the volume is set to an audible level and that the mute function is turned off.

3. Inspect Fuses

Locate the fuse box (refer to the owner's manual for specific location).
Remove the cover and check the fuse related to the audio system (typically labeled "Audio" or "Infotainment").
Replace any blown fuses with the same amperage rating.

4. Test with Different Audio Source

Connect a smartphone or another audio device to the vehicle using AUX or Bluetooth.
Play audio to check if sound is produced from the speakers.
If sound is heard, the issue may be isolated to the head unit or original source.

5. Inspect Wiring and Connections

Remove the head unit using a trim removal tool and screwdriver.
Check all wiring harnesses and connectors for secure connections.
Look for any signs of damage or corrosion on the connectors.

6. Test Speakers

Use a multimeter to check the resistance of each speaker.
Disconnect the speakers and measure resistance; typical values are between 4-8 ohms.
Replace any speakers that exhibit an open circuit (infinite resistance).
