Ya have to pull the cover off.
Its the one with three screws.
Don't worry its just a trim cover. Oil will not gush and theres nothing under it except the arm that the cable attatches to.
If that arm is free and the cable doesn't move...you need a new cable.
if that arm doesn't move...ya need a shop manual.
Seriously if it doesn't move its not that hard to get it apart and fixed. Come on back and someone will tell you how. (but a shop manual is still a good idea)
