What's wrong with my rear wiper???! on 2004 Chrysler Pacifica

When I turn my rear wiper on the first setting it won't move, when I turn it on the second setting, it will go but when I turn it off it stops randomly in the middle of the window. I just put new wipers on it 2 weeks ago and then it does this! Help please!!!!

Simple fix, IF at the time you can still hear the wiper motor running......Tighten the retainer nut at the base of the wiper arm... With wiper AND wiper motor in the 'parked' position! ... You loosened it up when installing the new wiper... Have seen and 'fixed' this problem many times!!!!
