The driver side wipe was stuck from ice. The passenger side works fine. I just wanted to see if there was an easy fix or had to go into the shop.

There is a nut that holds the wiper arm on at the pivot point at the cowel. Remove the plasic cover and you will see the 13mm nut. Be sure wipers are in the off position then position wiper correctl on windsheild then tighten nut. The plastic cap may give you a bit of trouble to get off.
