Then someone has added to it. look at the O-ring connections and
you see the telltale signs of refrigerant oil.

Re: A/C problem
hey doug, just a correction for you on the two lines going to the cab. only
one should be cold. The smaller one should be warm, and the larger one going
to the compressor should be cold. If they are both cold, then there is a
serious problem. The system would be under charged as the refrigerant would
be flashing through the liquid line going into the cab making that line cold.
It should have a solid column of liquid refrigerant, and thus be warm. It
doesn't get cold until it reaches the metering device, and the refrigerant
flashes to vapor. Now, the smaller line should be cooler than the line
coming out of the compressor (discharge) line, but it should not be cool or
cold.
