Different style rear wipers for 1st Gen?
When I bought my 86 it had the rear wiper arm in the trunk. When I finally got around to putting it back on, I notice it doesn't seem to line up right with the little cradle on the hard top. The motor works, and it drops down onto the window, but when i turn the wiper off, it doesn't go up onto the cradle to park. What's weird is that it I press the switch on for about a second, it will continue up and park itself, and then I have to turn the switch off really quick.
I am wondering if I maybe got one from a 2nd gen, or if the wiper arms are different on say 84-86 and then 87-89 use a slightly different style? Also, since putting this wiper arm back on, my rear window is much more finicky from the switch. It rolls down, but won't roll back up. I assume this wiper has something to do with it.
I think I actually need the one with the short stubby slide (copied from an ebay ad.)

That is a 2nd gen one. I use a 2nd gen on my 87'. i just cut mine down, I looked at some first gens online and then went to town with a hand grinder and then fine turned the aluminum slide with a bench grinder. I did bend the end of the arm ever so slightly to make it seat in the middle but I do not think it was really necessary.
the window will only go up if the wiper is seated in it's stop point, it is just a but long with the 2nd gen one. You can make it work with some fabing or try to get a 1st gen one.

Correct, that's the wrong wiper arm. Here's what it should look like....
When wiper arm is not parked all the way, the park switch grounds a pin on the rear window control relay module. This keeps window from operating. To test this / eliminate doubt on wiper parking, disconnect the connector at the rear wiper motor assembly and try again.
I find the rear wiper more trouble than what it's worth (sedans and trucks do not have rear wipers but that does not seem to be a problem), and I want to clean up that area. That's why I removed mine and am selling the whole assembly. Unfortunately (according to Toyota Parts Deal), wiper arm PN 85190-89133 on my 1986 will not fit your 1988.

that seems odd. hard to believe that toyota changed the rear wiper during the run of first gens, unless the wiper was problematic right away, and they had to redesign it. otherwise, why reengineer something that admittedly has limited utility even when fully functional?

I agree they are a pain, but I'm trying to restore this 4runner to factory so I don't like when things don't work.

Yup. Toyota should have fixed the starter relay and headlight circuits, instead.

That’s what mine does too on my ‘88. I have to “quick hop” it with a momentary flick of the switch to park it off the window completely.

Now the real guts of the question. Do they all do this and have they always done so or is it wear on the mechanical bits, like say that nylon bushing on the right side of the picture above? Any of our original owners want to chime in?
PS mine does this also, its part of my exit process to make sure it's fully retracted in case I want to open the back end.

mine used to do that. i found that the spring/arm and joint needs to be well-lubricated, and then it won't hang up when the arm is moving to its "park" location. i've been using fluid film liberally applied to the wiper arm linkage/joint. now the wiper parks when the switch is turned off, instead of having to briefly "hit the switch again" to park it.

I’m going to try this today since I’m replacing the bolt cover. It will be interesting to see if it fixes the issue. I was pretty sure that wasn’t how it was meant to work. Also the part number RAD listed comes back as fitting on my ‘88.

Until then,
I did pull the arm completely off and ran the wiper through the full cycle and it "parked" itself and I heard a relay click. The window still won't go up from the switch. Just down
