I too have had some squeaks... Check the plastic molding around your dash... where the pieces come together. Sometimes they get loose, and all you have to do is push them back into place until they snap into position.
It sounds like the rattle many others on this board have had. It comes from the plastic cover in front of the windshield. That's the cover the windshield wipers go through. They have said that the clips don't hold it real tight. Try pulling it off and putting it back on. You might have to squeeze the clips a bit with pliers to make thm more snug.
