Yep...I just changed my right side vent.
Start up close to the windshield above the tweeter cover and pop off the plastic strip. That will allow you to then lift up the tweeter cover, gently, and that will expose the two screws holding the vent onto the dash. The vent just pushed into the plastic air duct for the AC.
What I found is that there is a little wire that "sits" into the vertical plastic panes inside the vent housing. When you move them side to side the wire keep the panes in alignment and moves them in unison.
