ok, my '97 ac is only blowing 50º to 60º. it has a sticker saying it was serviced back in february (doesn't mean much to me seeing the situation), and i have a hard time believing this is as good as it gets. the compressor cycles normal, but i have no way of checking pressures.
i'm a mechanic, but i'm AC illiterate. please help, i've got a 3200 mile trip to make next weekend in 115º heat.
