Tom,
This part of your problem is very easy to fix -- just remove both wiper arms
and replace in the proper parked position. The shafts coming out of the cowl
are splined, as are the wiper arms. Just rotate the splines till they match
up where you want them.

Yes, there is a limit switch in the wiper motor, and its purpose is to park
the blades after you turn off the wipers. They rotate till they reach the
parked position, and then the motor turns off. For description of this go to:

I would assume that once the blades are in the proper parked position,
movement at speed will no longer occur.
Hope this helps.
