The 2004 Toyota RAV4 takes 22" drivers side 19" passenger side replacement windshield wiper blades. Note, when buying windshield wiper blades be sure to always use the application guide book at the store, or now-a-days you can Google 'lookup wiper size'. You want to look this up because correct wiper fit is more than correct length, it's also proper attachment. Not all attachments fit all arms. Using the application guide or looking up wiper size online will avoid headaches of buying the right lengths with the wrong attachments.
It also takes a special 12" rear wiper blade for the special rear arm. Your dealer will have them (may be expensive) or you may want to look into "Trico Exact Fit Rear Blades" that fit these new special arms - you can find them online. (there may be others available too). The good news is - specialized rear arms do not automatically mean the wiper blade is difficult to change - it just means you need to get the right blade for easy (and successful) installation.
