Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect Body Panels and Seals

Check for any visible gaps in the body panels, especially around the doors and windows.
Use a flashlight to examine the door seals for cracks or tears. Replace any damaged seals using the following steps:
- Remove the old seal by peeling it off.
- Clean the surface where the new seal will be applied.
- Press the new seal into place, ensuring a snug fit.

3. Examine Windshield and Rear Window

Inspect the windshield and rear window for signs of improper sealing, such as bubbling or gaps.
If necessary, remove the trim around the windshield or rear window to access the adhesive.
Apply new sealant if gaps are found, ensuring it is a quality automotive sealant designed for windshields.

4. Check Under the Hood

Inspect all hoses and connections for signs of wear. Tighten any loose connections.
Look for any aftermarket modifications that may not be securely fitted, such as air intakes.
If any components are found to be loose, secure them properly.

5. Test Drive

After making the necessary repairs, conduct a test drive at highway speeds to confirm the whistling sound has been eliminated.
