What size are the wiper blades on a 2004 ford expedition?

The 2004 Ford Expedition takes 20" wiper blades on both sides front and a 17" rear wiper. See sources and related links below for more information. Since there are over 22 different wiper arm attachments, do not buy wipers just by length only - be sure to lookup exact wiper blade part numbers by vehicle make, model and year for the brand wiper you decide to purchase. This ensures correct length AND correct attachment.
