Wiper Motor Issue -Plz Help

All,

Having an issue with my new A body (70 Duster). The wiper motor looks new but when I turn it on, the wipers go from full down to about 2 inches up then full down and stop.

I also noted that I can raise the wipers by hand about half way up the window and then they stop and I can push them full down. When I disconnect the arm from the wiper motor it rotates 360 degrees at both speeds.


The wiper motor looks new and the previous owner stated (??) they worked fine for him.

Please help.
