So I did some work on nailing down the A/C issue today. The compressor turns freely by hand and I can't find any leak dye anywhere with a UV light. I need to take the belly pan off and check continuity of the compressor clutch as it isn't engaging and the CCU keeps registering the clutch code immediately after clearing it.
Some photos from the garage. Please excuse the crud; half the garage is currently storing my parents' stuff while they build their new one.
