Solution

1. Preparation

Gather tools: multimeter, flathead screwdriver, socket set, and OBD-II scanner.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Refer to the fuse box diagram to identify the audio system fuse.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace it if blown with one of the same amperage.

3. Inspect Speaker Connections

Remove the door panel or access cover to reach the speakers.
Check wiring harness connections for secure attachment.
Inspect speaker wires for any signs of fraying or damage.
Reconnect any loose wires and repair or replace damaged wiring.

4. Test Speakers

Using a multimeter, set it to measure resistance.
Disconnect the speaker from the audio system.
Place the multimeter probes on the speaker terminals; a reading between 4-8 ohms indicates a functional speaker.
Replace any speaker that shows no continuity or an open circuit.

5. System Reset (if applicable)

Reconnect the battery terminal.
Start the vehicle and turn on the audio system.
Perform a factory reset of the audio system according to the owner’s manual instructions.
