2009 Pontiac G3 AC Probs (DIY diagnosed and repaired! With pics)

I should really be much better at this than I am. I studied mechanical engineering at university, and had the refrigeration cycle drilled into me during our thermodynamics classes. It's just figuring out where everything is on this car and what measurements are considered normal. I'm gonna spend the rest of the day researching and then I think I'll have a crack at it.
