How in the world do you remove the little circle piece that goes around the climate control ****? Ive managed to dissassemble all the rest of the waterfall assembly, other than this circle part.

 

has nut you need a deep socket to reach it take it off and washer. take off the screws on the back the hold the hvac to the bezel and theres little tabs that still hold the hvac to the bezel just take your time separating it

 

I got it.. it didnt have a nut or anything. just some tabs that needed to be pried up a hair and then i was able to turn it and pull it out.
