steve,
it sounds to me like the linkage doesn't have enough travel to open the
park switch inside the motor. It may be that the motor can be turned
slightly in it's bracket to give it the extra little bit it needs.
Could also be that the joints in the linkage are tight and the motor can
quite pull it to were it's supposed to go.
First thing I would try is to take the wiper arms off, not just the
blades but the whole arms, if it parks then, replace the arms just short
of touching the windsheild rubber.
these are all just guesses, let us know how it works!
