Default HVAC help needed!!!

So i'm trying to get the HVAC computer off of the dash piece. I took out the screws so i could take the black cover on top of the circuit board off, and then i took out the screws on the circuit board (don't know if that'd be good for anything). It wouldn't budge. It seemed like it was stuck on the temperature ****. How do I get the **** off and how do i get the computer to separate from the dash??! Thanks

I don't know how to include pics....but i have some if someone can help me.....

don't do what snoop said, first of all, search for the DIY on the led swap, there you will find out how to take that off, but for now I will tell you:
1. remove the **** for the hot/cold control
2. remove the nut that is behind the **** and the board will be free after you remove all the screws

to add on.. the whole HVAC assembly can be removed first.. (don't pull off the back cover..)

instead.. once you remove the 6 screws holding it in, from the front.. push on the buttons to push out the unit... that's easier than trying to pull off the a/c ****.. it'll just slide out instead.

then remove the nut behind the a/c **** with a socket wrench.. (believe it's 10mm) and then open up the unit... you'll see 6 screws.. but only 4 of them need to be unscrewed for you to be able to pull out the circuit board.. (its the 4 in the corners) the other two are for the lcd... (NOTE: remember to pull off the hazard button)

if you're planning on swapping out the leds in the clock (you'll need to remove those other two screws)... which then good luck, because you'll need good desoldering skills so as not to crack the lcd.

(follow my instructions to remove the ****.. it's easier... just remove 6 screws and push on buttons to push out unit.. have the **** slide off)

(necessary for swapping out leds (unless you're doing red))
