my drivers side windshield wiper decided to quit yesterday...

is this an easy replacement or do i have to climb in through the inside of the dash or something? haha...

i'm pretty sure it's the motor that powers the wiper because it slowly died over three last "wipes", rather then just freezing on a spot which would make me think a connection was severed

 

That is an easy fix. Remove the cover on the wiper arm pivot, use a socket wrench and retighten the nut that hold the wiper arm to the wiper mechanism.
