Can the reverse motion be adjusted so the wiperarms dont stop at the top of stainless! Nothing are binding i can easy pull the wiper the rest area on the stainless without force
All wiper parts are correct to the motor all grounds ok plus extras added to the switch panel! And the motor does reverse just not anough!
And the stainless has no more than aprox 2 mm air over the windshield, so no huge gap
Not sure if this has the answers, but it has some good info on wipers.

The manual has some info too. make sure the motor is correct for an E-Body (077) or has been re-clocked.
Are they trying to park when they stop at the stainless ? By that I mean if you switch them to park, they stop at the stainless, if you just pick them up a bit, to they jump down into the parked position, or are they not trying to park at all ?

Could be that , if thats the case its sensivetive to the stainless edge

They can be....try it, see what happens...make sure the key is on or the car still running
I've had this happen to me years ago too. I don't recall if it was in the clocking as in the above diagram that was the fix or a broken piece of plastic on the gear that leads the wipers to the park position.
The motor do reverse but not anough wiperarms seems loosely but there are no play in the bushings etc!
The motor Is a ebody motor , can the reverse motion be adjusted for
More motion?
Pic of the plate
What year is your car? Has the wiper motor been rebuilt?
Looks like an important portion of your switch plate picture is cut off, it's clocked positioning tip. My picture is of a '70 - '71 wiper motor but I believe all years should be clocked the same way. The first picture in Cody's Reply#3 shows it as "Barracuda and Satellite".
that looks like the wiper motor from a later model aspen. I pulled one like it from a pic and pull yard and installed on my 71 barracuda to replace the 2 speed as I had installed a shaker. I had to rotate the switch plate about 30 degrees to make it park and it works great.
The motor is a 73 3 speed
The switch plate looks at least close to where it should be. Take the crank arm off the motor and post the part number and the number on the drive arm, the one that goes from the motor to the left wiper transmission. That will tells us what you have and what year it came from. 70-71 are the same and 72-74 are different. Onec you have a baseline we can make it work.
All part no are correct as i mentioned earlyer...
Its a 72-74 3 speed motor crankarm and link arm.
Crank arm 3431518
3431 514 link arm
3431665 motor
1. Remove both wiper arms.
2. Remove the linkage.
3. Check all the linkage bushings and pivots for wear.
4. Check the wiper arm pivots for wear they should be tight.
5. Make sure the motor is clocked per the diagram in a previous post.
6. With the motor installed run and park the motor.
7. Make sure the linkage and pivots are installed per the FSM, you should not have to force anything. If you don't have an FSM mymopar.com has it under resources.
8. With the linkage installed and the motor parked put a horizontal mark on each of the wiper arm pivots.
9. Run the motor and observe the marks to see how far they sweep and if they return to park.
10. If the wiper arm pivots sweep and park you should be able to install the arms and run the system.
Pivots are tight no wear,no wear on linkage bushings.
But it still wont park the wipers on the stainless center
The motor runs all 3 speeds and off it reverse park.
So you're saying that the wipers work on all speeds, when shut off they do that little reverse jog and go to the park position, but that position is too high ?
When the wipers are on full speed, how close do they come to the A pillar windshield trim ?
Maybe you have to reposition the wiper arms on the pivots ? :dunno:
The linkage that goes between the two wiper transmissions has a tab on the end marked R, make sure the tab is 90deg to the rest or the arm it can hit the pivot and stop the parking early
I will post pictures of the arms ,where they are in park and highest on windshield
Here is a picture of highest point anl lowest when running
Aren't the wiper arms splined? Is it possible they are just in the wrong spot? So they work fine, but maybe go to far over and not far enough down? When they are parked can you push them all the way down to where they should be parked or are they parked and only move a little bit?
I can push them over the stainless to where they should rest
If your still having the problem I'll repeat what I said earlier up thread. I think it could be part of your parking cam plastic that may be broken as I had a problem like this once too. Pull the plate and look at that plastic cam behind it. Cody posted a pic. I believe the part that parks is at the 10 O'Clock position, but check for any breaks in general as my memory could be off.
I think the system is working fine and the wiper arm is just hanging up on the stainless...common problem ...tweak the wiper blade to give it more of an arc. :alan2cents:

This was another fix for this problem. You may need to pull everything out and start over inspecting them as you go.
What tab?
The linkage that goes between the two wiper transmissions has a tab on the end marked R
You would have to remove the linkage and pivots to see it
This is the tab that Ns1aar is referring to.
If everything is assembled correctly I personally think you have worn brass bushings that are worn just enough to have the blades hang up on 2mm of "lifted" stainless trim. I know you said there's no wear on the bushings but if they're not new then there will be wear, it doesn't take much.
Any email i can send it to im overseas ;-)
I have a nos link arm from crank arm to pivot. And there were no slop in the center arm between pivots
I think its the stainless that makes the trouble. Just cant see how a 2mm gap should make the motor not park the wipers , these motors are powerfull...
You got mail
Anyway to post the video here ?
i think the video has to be hosted to a site like youtube and then linked here.
Let's try this
https://youtu.be/SAXGfu4uwwk
That video link worked thank you for taking the time to set that up...Makes answering his question a lot easier. :twothumbsup:
Like I said eight days ago, and now you've suggested it...just adjust the arms on the pivots. ;)
BUT BEFORE doing that, I would suggest what I said three days ago...bend the center section of the metal wiper blade to give it more of a curve, it looks flat in his video. By tweaking the wiper blade, you'll raise the arm up enough to clear the stainless steel trim in my opinion, that's all it will take :alan2cents:
You have a huge gap with that stainless. I bet if you just flatten it against the windshield (don't ask me how) your wipers will park AOK. Your picture with the up swing at the A pillar looks normal to me. I wouldn't do any repositioning of the wipers on the splines until that stainless was flat. If you want to go through the trouble of actually removing the stainless my guess is the blades would go all the down without any assisting. As usual this is just my opinion.
So everyone can see it in case this questions comes up again. Like many have said, the splines can be adjusted and that is all that is needed. Everything is working fine. The wiper arms just need to be adjusted a few splines.
What refill/wiperblades to choose then
Did you get it to work
