The Year Without a Santa Claus (1974)

Mrs. Claus tells us about the time Santa had a bad cold and decided to take a vacation from Christmas. Two of his elves, Jingle and Jangle Bells, decided to go out with Vixen to find children to convince Santa that the Christmas spirit is still important to everybody else. But they must get past Heat Miser and Snow Miser before they land in Southtown, USA, where it never snows for Christmas. Heat and Snow can't agree to let this change, but Mrs. Claus knows their mother, Mother Nature.
