 Posted: Sat Jun 15, 2013 10:07 pm Post subject: Windshield wipers out of sync |
 |
|
Ok, this one has me perplexed.
I changed out the wipers on my 81 Vanagon and now the drivers side I won't work. If I help it with my hand it still falls out of sync.
The passenger side works perfectly fine.
Is this a worn out motor?
To ensure it wasn't just a dry windshield causing the problem I sprayed the whole thing down with windex and no change.
ARGH!!!

| Try cleaning the splines on the wiper shaft and wiper arm. Sounds like the wiper arm is slipping on the shaft. |

Hmmm, my creative Google'ing is coming up dry on how to do this. Do you have any resources I could check out?
TIA,

Holy moly this worked like a champ!
I don't know if the before pics will do this justice but they were smooth to the touch. After I cleaned them they had grooves again and work beautifully.
Thanks again everyone!

| As mentioned in the linked to thread above you need a washer with a big enough hole to fit down over the splined part of the shaft. With out a proper washer the stripping of the splines will just reoccur in short order as all you are doing is tightening the nut against the shoulder on the shaft and not against the eye of the wiper arm. Don't have a source for an off the shelf washer that will work, I have always just had to grind down the circumference of a washer that had the correct size hole. |

Yeah, I guess you can't see it in the pic but the two washers are there.
One thing of note, the video said this was a 6mm nut but mine took a 10mm ratchet to remove.

The wiper shaft is 6mm, a 10 mm wrench is needed to remove the nut but it actually is considered 6mm.

What it looks like to me is that I am seeing the stock washers. Could easily enough be wrong as one just can't see much with all the pieces installed. 
The stock flat washers are the cause of the problem, they need to be replaced with washers that are thicker and have a large enough hole so that they can be slid down over the end of the splines. If the replacement washers is what you have, then great. |

Thinking back on the repair and rewatchng the video a couple of times, I do see now that I do not have the warped washer on the second one to provide the torque. I will have to make a trip to the hardware store and see if I can find something.
