I'm thinking it'll be in the cam assembly, probably gonna need to dig into a service manual for this one....

As you can see in the video, seems like there is some wiggling in the cam assembly.......maybe someone can say if thats normal or not??

I haven't owned a car with two speed wipers in over 25 years & back then I owned a couple parts cars never a running driving car so I've never really paid attention.....  Looking at pictures it looks like the plastic cam could wear & not effectively drive the arm.....

Between the video & just logic it really looks like the cam is where you problem is... I've searched Ebay for parts & there isn't much, one guy has a incomplete setup that he wants $145 for.... I'd wait & watch, lots of folks replace the two speed stuff cause getting a good motor & switch can be a challenge, you've got both of those, just need the stuff thats normally not a problem....   If it were me, I'd look for a complete really nice part it should have the rubber boot that keeps dirt & debris from getting in & causing wear, a nice drive cam, probably a couple springs & clips... And a drive arm with good drive lugs....

After looking around some more it appears they reproduce the plastic bushing.....   I'd give one of these guys a call....

I tore apart the linkage today (that little metal retaining clip holding the crank bracket to the motor SUCKS!  LOL)

So here is a pic from the svc manual --



I seem to be missing some parts.....the "spring washer" and the cover are obvious ones.....the whole cam assembly is sloppy when assembled....

But also the cam itself may be damaged?

Also looks like the metal part on the top of the pic irectly below has a groove worn into it....















I have no idea what this is...is was lodged in the drain hole directly under the wiper motor/crank area.....  Its plastic....





Found this picture on ebay of a parts kit 


Anyone have pics of their parts so I can compare??

That thing you found looks like the rubber seal on the end of the motor, first picture.
That "groove' is definitely not suppose to be there and it seems you're missing that special spring.
The rest of the pictures show one that I took apart (kind of in steps).

Sorry, after looking closer it looks like you DO have that coil spring with the oddball end, though it's hard to tell if it's broken anywhere.

You do not have electrical problem
 if it stops any place on windshield. You have an open park circuit
Your issue is worn parts and lubrication.
The rubber grommet you cannot identify I believe is the cover retainer that covers the
CAM next to the cam arm.

Do you have the correct wiper arms?

Maybe a stupid suggestion but this happened to me and I found that I needed the car to be running to get the wipers to park correctly?  Not sure why . . .

Nope.....doesnt matter in my case.....its something mechanical at this point I think given the state of the parts....

I should have directed you to Kim

Contact Kim  she restores and sells parts for wiper motors.


kim@passion4mopars.com

I'd start with cleaning up the parts looking at the wear and tear.
Purchase the parts kit if it fits your setup.
The slot on the cam arm looks worn.
Kim knows a lot of us on here.

Thanks! I will try Kim.  I was under the impression she just does the motors.....crossing my fingers!

Here's a thought. What if the previous owner moved the wipers on their splines to compensate for an inadequate arm sweep due to the deep groove pictured. Then consequently the reverse (park) travel would be affected.
