48* air is pretty normal for a car air conditioner (thats what my Fit, Xterra, and Subaru all do). Check the low pressure hose, if it's cold at the compressor, the A/C is doing all it'll do. I checked a PT chart for R134a, 45 psi on the low side looks about right for Las Vegas' high ambient temperatures. Do you use fresh air mode or recirculate? Above 90* fresh air doesn't do it for me, recirc. is barely adequate. New R134a car air conditioners just don't do it like the old R12 (CFC) ones.
