Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery for safety if working on electrical components.

2. Inspect and Replace Weather Stripping

Sub-steps:
1. Remove any interior panels or trim that obstruct access to the door seals.
2. Inspect the weather stripping around the doors and windows for cracks or deformation.
3. If damaged, carefully remove the old weather stripping using a trim removal tool.
4. Clean the surface where the new weather stripping will be applied to ensure adhesion.
5. Install new weather stripping, ensuring it fits snugly without gaps.

3. Tighten Loose Exterior Components

Sub-steps:
1. Identify and tighten any loose screws or fasteners on exterior panels, including the front fascia, hood, and wheel wells.
2. Use a torque wrench to ensure that bolts are tightened to the manufacturer's specifications.
3. Inspect the underbody for any loose or hanging components and secure them as needed.

4. Test Drive

Sub-steps:
1. Reconnect the battery if it was disconnected.
2. Perform a test drive at highway speeds to check if the whistling sound persists.
3. If the noise remains, revisit previous steps or consult with a specialist.
