I refilled my ac on my truck (f350) and the ac blew cold (for about a month) and the last month it started blowing warmer and well I thought maybe the orifice tube got plugged up. So I take it off today to install a new one and it seams like my ac system is full of water or something like that. it is not oil it is more like water. and the orifice tube was covered with what looked like pieces of leaves but the system has never been left open for more than just the time I was changing o rings. Could it be the dryer coming apart? there was no metal at all in it. Any other ideas btw it didn't take any time to vac it down and when I put one can in it the low side was around 85# and wouldn't take anymore freon.
