I can't help you with the washer part of your question but I can help you with the wiper blade part:
The 2005 Dodge Grand Caravan has the most common hook-end wiper arms on front and rear. See sources and related links below for installation videos. Also, purchase the replacement blades first and there will be additional instructions/illustrations on the replacement packages. Locate and press the tab or button where the wiper blade is inserted into the hook of the wiper arm and pull wiper blade out of hook. You may have to rotate and flex the blade to make enough clearance for the hook to pass through.
