71 c10 ac questions

So I have been in the process of completely redoing the ac on my 71 C10, and I have a few questions. The first, which I am working on right now, is what the hell is this thing?? It seems to be a low pressure switch? I'm not sure but I haven't replaced it because I don't know what it is or does, and needed some help. Also, I have been trying to blow through the system with air and it is getting blocked somewhere by the evap, I'm thinking that that switch, or the valve in the second picture is closed and not letting anything through. Any help would be appreciated. Thank you.
