New '13 owner... bought the car after a CPO / warranty inspection from an AM dealer. But the passenger side wiper doesn't work. Anyone had this issue? No problem taking it in locally to get fixed under warranty, but would love a 2 minute garage fix if it's possible.

Basically, the wiper motor(s) sounds like it's working on both sides - the drivers side blade arm moves fine, but the passenger side doesn't move and there's a bit of a grinding sound. hmmm.

anyone dealt with this one? searched but haven't seen it described online...
