Repairs:
Repairs associated with external wind noise are usually straight forward. If panels are misaligned, or moldings, trim or other components are loose, just make the repair according to the shop manual procedure.
Repairing internal wind noise is also usually straightforward. After you've found the location of the leak, the appropriate repair should be apparent.
Check the appropriate service manual for the proper procedure if you're not sure how to adjust a component.
When adjusting a door, be sure not to create any gaps that may cause a new wind noise.
Some conditions can't be fixed by realigning components. If seals or weatherstripping need to be repaired, there are a variety of adhesive sealers and related products available. A convenient chart in the back of this bulletin lists some of the materials.
You should also be aware of any service bulletins or training materials that may be out on a vehicle you are working on. They can save you valuable time.
