I do not see aftermarket replacement wiper blades nor wiper refills listed in the aftermarket wiper catalogs. This would possibly indicate that the rear wiper was a proprietary Toyota technology/design and you may have to go to the dealer for the parts and possibly labor. Before doing this (because its usually a little more expensive), you may want to visit some internet forums and see if there's other ideas out there. Google "toyota 4 runner forums" then search "rear wiper" once in the forums. I'm sure there's rapport on this topic.
stick the wiper blade up your hole - I can't figure it out either.

The 1994 Toyota 4Runner takes a special rear wiper you have to purchase at the dealer. When purchasing the part, ask for the replacement procedure. Unfortunately, this vehicle doesn't have one of the 13 universal rear wipers most vehicles have. You can however purchase aftermarket wiper blades for the front wipers.
