We messed with those wipers on our 4Runners for awhile, but i've now come to the conclusion that the cap on the 4Runner is really just a glorified topper. I don't have a wiper on either of my toppers, why do i need one on the back of a 4Runner? You don't see them on the rear windows of many vans, either. Probably the manufacturer of an SUV is just required by law to have a wiper on the rear.
So now i just remove the motor and wiper, and fiberglass over the holes. A little paint and it looks factory, and i don't have to worry about it failing, or the window refusing to go up or down cause the wiper isn't in the perfect position.
i will admit taht this is not a need, its a want. i want everything on my rig to work, i just spent 2 hours aiming the headlights for poops sake
