Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, screwdriver set, and a flashlight.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical hazards.

2. Inspect Air Intake System

Remove the engine cover (if applicable) using the socket set.
Check the air filter for blockages and replace if necessary.
Inspect the intake hoses for cracks or loose fittings. Tighten or replace as needed.

3. Check for Exhaust Leaks

Inspect the exhaust system for any visible signs of wear, cracks, or loose connections.
Use a smoke test if necessary to identify any leaks in the exhaust system.
Tighten any loose bolts or replace gaskets if leaks are found.

4. Examine Body Seals and Trim

Inspect all door seals, window seals, and trim pieces for integrity.
Replace any damaged or worn seals that may cause wind noise.
Ensure that all clips and fasteners on the body panels are secure.

5. Reassemble and Test

Reinstall the engine cover if removed.
Reconnect the battery and start the engine.
Take the vehicle for a test drive to confirm that the whistling noise has been resolved.
