Jon,
Try opening and closing the on/off switch with the motor running. If that
moves the wipers back and forth, then the unit is bad. There is a valving
mechanism in the back under a thimble sized tin housing. You might try to
gently pry that off with a knife and then spray some WD40. It worked on my
old old unit.
Good luck.
