I would check where the wiper arms attach to the spindle as well as the linkage to the motors. I have purchased wiper parts for my Newell from these guys.

I am in Northern Indiana. Just wondering how close you are?

I am just south of Grand Rapids, in Dorr, MI.
Wippers lifted, then stopped moving. I had to manually move them back to the upright position.  They moved with very little resistance.
