Is there an article that explains (pictures maybe?) what goes on in that little machine?

When you shut it off, power is directed to the motor to "Park" the arms. What opens that circuit?

How do the arms change direction to park?

Thanks for any links of info. Neil

my memory is that the park feature is a constant hot (in run) circuit that breaks the ground path when the motor reaches its "park" position. For the reversing to park units I believe that the park circuit is reverse polarity to normal units.

This may all be completely wrong info I haven't looked into wipers wiring in quite some time.

this is a quick search of 2 speed units, 3 speed is more or less the same with another speed.
