passenger side wiper not working on 1996 Cadillac DeVille

Does anyone know why the passenger side wiper won't work?
The driver side wiper works fine.
Is this an easy fix?

Check the fastener for the passenger side wiper that holds the wiper arm on to the pivot, it may be loose, other wise it is most likely loose or disconnected wiper linkage.
