Dash Disasembly?

Has anyone attempted to disasemble their dash yet, specifically the passenger area, and have any recommendations/instructions on how to do so?

Little background, I have the vibration some of us have at the 2100-2300 RPM range, and there's something on the lower portion of the passenger side that loves to vibrate/buzz. It's starting to drive me nuts.

 

I had that SAME buzz .... I thought it was just the cold, but I redid the glove box shelf and I haven't had the noise since. I originally thought it was the speaker, but the stereo was off. I am curious if you find something else.

 

Unfortunately I've already tried removing the shelf, and also dynamating the door and removing the speaker and surrounding trim. No luck so far. I'm thinking either something in the dash or some component of the power window.
