Get into the wiper motor. I guarentee(sp) one or two white caps fell off. Just put them back(clue them). Make sure you add grease to the arms.

It is a no brainer. Anyone can do this. You will not damage anything. The caps are shaped like a hemisphere and snap in to hold the wiper arms in place.
Lack of grease pushes the cap off after a decade. When mine fell off I glued it and applied lots of auto grease.

Dealer said you have to buy the whole arm.
