Last summer the AC would work for me one day and not the next, this summer we got nothing out of it. I was confident that I just needed to recharge A/C so hooked up the meter from a recharge kit and instead of an expected low reading it was off the chart, like maxed out gauge 350psi or something like that....

Anyone have a clue what the problem is???

yeah our cars cant be serviced with those crappy recharge kits at the auto stores. its mostly for older cars. you gotta take it in to an ac shop and have them hook both lo and hi ports to a machine to drain and refill. and if its not getting cold, chances are you have another problem like leak in the line or some failure either compressor, dryer, or other part. its a closed system and you should not lose any r134a over time unless its leaking

sounds like you hooked it up to the high end. is the system charged? does the compressor kick in when you turn on a/c?

maybe its the pressure switch thats malfunctioning.

its normal. and hi pressure port is too big to fit lo pressure connector. i have very high pressure and my ac works fine.
