Solution

1. Preparation

Gather tools: Screwdriver set, multimeter, OBD-II scanner, and wire connectors.
Ensure the vehicle is parked, and the engine is off. Disconnect the negative terminal of the car battery to prevent electrical shorts.

2. Inspect and Replace Fuses

Check Fuse Box:
- Locate the fuse box (usually under the dashboard or in the engine compartment).
- Identify the audio system fuse (refer to the owner’s manual).
Replace Fuse:
- If the fuse is blown, remove it using a fuse puller or pliers.
- Replace with a fuse of the same amperage rating.

3. Check Wiring Connections

Access Radio:
- Use a screwdriver to remove the radio from the dashboard.
Inspect Wiring:
- Check all harness connections for secure fit and signs of wear or damage.
- Use a multimeter to test continuity in speaker wires.
Repair or Replace:
- If any wiring is damaged, repair with appropriate connectors or replace the wiring harness.

4. Test Audio Sources

Connect Different Sources:
- Test the radio with Bluetooth, AUX, and USB inputs to check functionality.
- If sound works with one source but not others, the problem may be isolated to the non-working source.

5. Reset Radio System

Disconnect Battery:
- Reconnect the battery’s negative terminal after waiting a few minutes.
Turn on Radio:
- Start the vehicle and test the radio functionality to see if resetting resolved the issue.
