Solution

1. Preparation

Gather necessary tools: screwdriver set, trim removal tools, multimeter, OBD-II scanner.
Ensure the vehicle is parked in a safe area with the engine off.

2. Check Audio Settings

Power on the vehicle.
Navigate to the audio settings on the infotainment screen.
Ensure that the volume is turned up and not muted.

3. Inspect Fuses

Locate the fuse box (refer to the owner's manual for exact location).
Identify the fuse for the audio system (usually labeled).
Remove the fuse using a fuse puller and inspect it visually or test with a multimeter. Replace if blown.

4. Inspect Speaker Connections

Remove the door panel using a screwdriver and trim removal tools.
Visually inspect the speaker wires and connectors for damage or disconnection.
Reconnect any loose wires and replace any damaged connectors.

5. Test Audio System

Connect a compatible Bluetooth device and attempt to play audio through it.
If sound is heard, the issue may be with the original audio source rather than the speakers themselves.
