Okay, after a fat finger episode, I will enter this again. I now have the dash rolling down on the dash pins to a degree, but the steering column only goes down so far and so the dash only goes down so far on top of it. I will look next at removing the wires and such; but it still seems it will not go down far enough to get to the A/C box under the dash. I also wonder just how the dash comes out at all since there are plates right above the dash pins that will not allow you to pull the dash up and off the pins. Any thoughts?
Any suggestions on replacing the rear expansion valve in a 99 suburban? I have the interior and all screws apart but i cant reach 2 screws between the fender and the black rear evap housing. I cant imagine I would have to disconnect all the lines from underneath? especially since service bulletin mentions cutting a hole in the box. How can i get to the last screws?

Unfortunately I have no advice on the expansion valve other than to say I have had to drill holes to get to screws in the past. Window motor on an 84 Thunderbird comes to mind.
There are videos on youtube about changing the rear expansion valve; maybe they can help.
