Has anybody disassembled the cooling unit under the dash, on the interior side of the firewall? If so, could you please tell me how to go about doing it? I think my expansion valve for the a/c went out, and I might need to replace it. I am pretty efficient at repairing things, but have not messed with this unit yet. I just need some directions.

Thanks in advance!

Ok, I partially took apart the cover that houses the cooling unit under the dash, but not quite all the way. I'm still working on that. However, I now have another question. When taking off the expansion valve, will all of the freon leak out? If so, how do I keep a vaccuum in the system so that all of the freon will not leak out?

you need to have the system evacuated before you remove the tx valve and then re-gassed when its been replaced and the system sealed again

I don't even know how you got to expansion valve without opening up system. You need to disconnect 2 AC lines at firewall (in engine compartment) and remove glovebox. Then remove 2 nuts that hold box and pull box out (1 connector to be disconected)
