I'm having problems out of my 94's a/c. The air coming out of the dash is barely cold. Nowhere cold enough for Florida's heat. The low side line is somewhat cold to touch but the high side is hot. I hooked a set of gauges up & got a reading of 40 low & 175 high. The sight glass is kinda milky with some bubbles. Any ideas or suggestions??

prolly needs a recharge, but if it lost any refrigerant, you prolly have a leak in the system that needs to be fixed first, otherwise it will just leak out again if you try to charge it.
