Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Weather Stripping

Tools Required: Flathead screwdriver, adhesive (if needed)
Remove any damaged or worn weather stripping around doors and windows.
Clean the surface where the new weather stripping will be applied.
Install new weather stripping, ensuring a tight seal to reduce noise.

3. Check and Repair Air Intake System

Tools Required: Socket set, screwdrivers
Inspect air intake hoses for cracks or loose connections.
If damaged, remove the old air intake hose and replace it with a new one, ensuring all clamps are tightened to specification.
Inspect the air filter; replace if dirty or clogged.

4. Secure Loose Components

Tools Required: Socket set, wrenches
Visually inspect all hoses and components in the engine bay for looseness.
Tighten any loose bolts or connections, particularly around the intake manifold and exhaust components.

5. Test Drive

Reconnect the negative battery terminal.
Start the engine and take the vehicle for a test drive to determine if the whistling noise persists.
