Desperation being the mother of something or other, I thought I had
better rejoin the list with the hope that I could get some help!

I was driving through a fairly heavy rainstorm with the wipers on high
speed when they all of a sudden changed thier range of motion to start
from horizontal pointing left and end straight up.  I stopped as soon as
I could and pushed them back to the normal neutral position at which
point they would not work at all.

Having wrestled the mechinism out of the van generally along the lines
recommended, the motor always parks in the same place and the range of
motion seems to be about normal.  In the process of extraction, the park
position was reset since I tried to detatch the motor from the arm in
the car.

So, at the moment the mechinism appears to work.  The question is
whether it is likely the gears or whatever jumped within the motor to
cause the park position to jump or if this is likely to have resulted
from the drive from the motor to the arms slipping.  In short, am I
likely to need a new motor or do I just reassemble the mess and get on
with it.

My supplementary question(s) concern extraction/reinsertion of the drive
assembly.  The bushing on the passenger's side required a lot of force
to depress it fully into the hole to facilitate extraction.  It was only
after changing motor position that it could be made to come out at all.
There seems to be some sort of obstruction which I cannot identify; is
brute force the correct extraction technique?  Any tricks for
re-insertion (other than lining up the linkage in the stopped position
as per the manual)?  Although I should not have to do this, I have all
the rear and side dash screws out but without messing with the steering
column it refuses to budge.

Any advice on this matter would be appreciated!
