FC Wipers pause in middle of windshield
I did search before writing this, but nothing quite matched the experience I'm having.
When turned off, the wipers will sit in the middle of the windshield. However, I've tried two switches now, and on both every setting works, it's just that it will stop in the middle of the windshield.
I first tried refitting the wipers on, but then I noticed that you can see the pegs, with the wipers off, will actually, when first initiated from a natural stop, move counterclock-wise, and then clock-wise, then counter-clockwise again before stopping, once more in the middle.
Is something hooked up weird or something in the motor? I'm not sure at all, thoughts?

No ideas? Haven't had time to pop off the cover and look at everything, hopefully this weekend.
Also, another quick question, it's an 86 automatic GXL, and I'm planning on doing a 5 speed swap also soon, does the NA driveshaft fit into the GXL LSD? I thought I read something about it maybe not, just want to be sure.

Not exactly. The middle of the windshield is for some reason now their 'default' position. If I turn the car on, then turn the wipers on, then turn them off (with the car still on) the wipers will move to the middle of the windshield and stay there.

Well depending on where they are (i.e. if they're basically in the vertical position - in the left hand corner), every old car I've driven has gone to the middle if you turn them off if they're in the verticle position. They usually only go to the bottom if you turn them off when they're past the half way point

There are two relays within the unit and one of them is responsible for returning them to the proper position when they are turned off. It's possible that both switches you tried are damaged. When you tried to refit the wipers did you try leaving them off and then turn the wipers on and then turn them off a couple of times to see if the mounting piece returned to the same position before putting the wipers back on. And did you use another switch that was for your particular model. Not sure if all S5 and S4 switches are the same as some are for verts perhaps while others have the rear wiper function and so on. And using the "advanced search function" will pull up other threads w/this very same problem as I have seen them before.

My wipers do the same thing. I have a 89' rx7. I just have to time mine right as to when I turn them off. So, I watch them for a minute and when they get to the very bottom I turn them off before they have a chance to pop back up.

Like I said the default position of the wipers right now is in the center of the windshield. They don't stop at the bottom at all, unless I time it to turn the key off when they're down there.
I've got it somewhat disconnected right now so I'll at least test the turning the switch to the 'off' position while the wipers are at the bottom tomorrow when I have time. I just find it difficult to believe it's the relay since they all worked on other cars. I only have two right now, but still, they tested okay.

Post #8 might help in this link. And did your wipers ever work properly or did you get the car this way? And does your car have the rear wiper feature?

The 'home' position for the motor is defined by a switch inside the motor. That switch only knows where the motor shaft is. The wiper arm position is defined by a) how the arms are mounted to the posts and b) how the motor arm is mounted to the motor shaft.
If the total motion of the wipers is correct, but 'home' isn't at the bottom of the windshield. I think that means the motor arm is not at the correct location on the motor shaft. That was the situation on the 88 vert I bought recently.
The windshield wiper section of the 'Body' chapter in the FSM (Chapter 14) shows the correct orientation of the wiper arm to the motor. Once that is correct and the motor's 'home' position is at the low point of the motion, then the arms can be mounted on the posts so they are at the bottom of the windshield.

Ah-hah! It's definitely the motor arm. I played around with it this morning, didn't get it quite exactly, but they both work and return to the bottom of the windshield. Taking the car into the shop today though, but will work on it when I get it back.
Just out of curiosity, why didn't they make each part have a notch so that it fit together in the way it's supposed to? Seems slightly odd to me.
Also, perhaps any answers on the NA 5-speed driveshaft fitting into the Automatic GXL LSD?

Sometimes links last for just a short period of time for some reason unknown to me. In any case just use the advanced search function and use "wiper park" as your search subject (keyword) and do this search within the 2nd generation specific section (forum) and you'll get a host of different results.

I have the same problem with my 86. What I have learned is that it is the combo switch. It is over $500 to get a new one. I have learned that if you keep the car running and cut the wiper switch off in the down position they will stay there. If they happen to move which has happened to me) use the same procedure even if is isn't raining.

Picture this Scenario:
Someone gets a FC for say 800 bucks,It is a Beater.
They start fixing it..to do What?..drive the Living Be-Jesus out of it and the track,Auto cross,show their friends that they can put the car sideways,,etc,etc,etc..
Do they go out and buy a 500 dollar NEW Switch??..NO!
they buy a 30 dollar USED Switch..(.Cough..Sec gen parts Section..).
The only time I see someone buying a NEW switch is if the car is a 9 out of 10.
That I can understand,but getting a 500 dollar switch for a Piece of "ahem"..??
I'd be questioning my Sanity if I did that!
