Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety goggles and gloves.

2. Inspect and Replace Weather Stripping

Remove any clips or fasteners securing the weather stripping.
Carefully peel off the old weather stripping from the door and window frames.
Clean the surface where the new weather stripping will be applied using a suitable cleaner.
Apply the new weather stripping, ensuring it fits snugly without gaps.
Reattach any clips or fasteners removed earlier.

3. Tighten Loose Hoses and Connections

Open the hood and visually inspect all hoses related to the intake and air system.
Use a socket set to tighten any loose clamps or fittings.
Replace any damaged or cracked hoses with new components.
If necessary, use duct tape temporarily to secure any minor leaks until parts can be replaced.

4. Test Drive

Start the engine and let it idle.
Take the vehicle for a short test drive to determine if the whistling sound persists.
If the sound is still present, re-evaluate the areas inspected previously.
