If your floor is insulated, hey should be open in the winter & closed in the summer. If you open them during the hot humid summer weather you just let moisture in.

If your crawlspace perimeter is insulated, they should be closed & sealed permanantly & an adequate vapor barrier be installed on the crawl floor.
