Remove the dashboard cover or panel where the noise is originating, using a trim removal tool.
Check for any loose screws or fasteners and tighten as necessary.
Inspect any electrical components (e.g., radio, HVAC controls) for secure connections.

3. Check Electrical Connections

Reconnect the battery and turn on the ignition without starting the engine.
Listen for the buzzing noise while checking for any faulty connections or damaged wiring.
If buzzing persists, proceed to disconnect and reconnect each electrical component one at a time to isolate the source.

4. Address Loose Components

If loose components are found, secure them with appropriate fasteners or adhesive as needed.
For any malfunctioning electrical components, consider replacing them with OEM parts.

5. Reassemble

Reinstall the dashboard cover or panel, ensuring all clips and screws are secured.
