It's not difficult. I'm sure there's a guide around here somewhere, but I'll go ahead and give you a brief explanation.
1) Pop out all of your A/C control knobs.
2) You have to pry out the window switches. Grab a thin piece of cardboard or wood and slide it in the gap between the switches and the center bezel itself. (Bottom works best) Use a flathead screwdriver and GENTLY pry the switch out. (First time you do it, you'll be extremely hesitant.. after that, it's easy)
3) Disconnect the harness connected to the window switches.
4) Unscrew the bolt at the top center of the bezel that attaches it to the frame of your dash.
5) Lastly, you have to pry off the center bezel, applying the same practice as the window switches. I have found it's best to work from the bottom edges, up.
And the age-old phrase applies, 'Installation is reverse of removal'.
Any questions-- feel free to ask.
