The 2000 Ford Windstar wiper blade sizes are 24" drivers side, 20" passenger side and a 16" rear wiper (if applicable). 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.
