The dash bezel is the aluminum facia over your guages. Three screws on the top and two long screws under the steering column cover...the one with the sivler a/c air flow diverter (you have to take this off to get to the screws).
The A/C ducts are under the dash. You pull the glove box and you'll see the big one...the expensive one. Check the manual for the screw locations. There are three ducts that you need to pull (four if you count the one behind the center air deflector) ...the big passenger duct, the one under the steering column and the one that connects those two....easy, just a couple of screws. But make sure you get all the screws and don't force anything and you won't break anything.
To get the dash bezel out, you need to take out the column cover mentioned above, the dash brace (4 bolts), and loosen the two steering column nuts but don't take them off....this will give you clearance so you don't scratch your column. Unscrew the cigarette lighter bezel...and slip off the dash bezel.
