Try something simple: just open and re-close the rear window. The window has a safety switch that keeps the wiper, washer and heater from working if the window is open. The window settles down (from opening and closing the hatch) over time the window settling triggers the switch. If you open and re-close the window it resets the switch and everything works again. My 2003 4 Runner does this over time. I just open it and re-close it to fix the problem.
No , a 2002 Toyota 4 - Runner is rear wheel drive or 4 wheel drive
This answer will vary depending on the year of the Toyota 4Runner. I do not see a rear wiper listed for 1992-2002 & 2010+, so if it has one, its a special toyota-only wiper that you can only get at the dealer. In that case ask the dealer how to change it. For 2003-2009 Toyota 4Runners, there is an aftermarket wiper blade available, but it is a fairly specialized design that is difficult to find in stores. See sources and related links below for information on the wiper blade as well as an installation video.

Either the wiper arm slides on the axle, or the wiper motor died.
