Ranger A/C Orifice tube.

This filter known as the orifice tube gets clogged more often then I thought. This is the second truck in which this tube was clogged with black goo and some cat hair??? Not really cat hair but dude that would be weird. The tube filter is usually inside the bottom line of the evaporator. Just inside the coupling. Make sure it goes in by the arrow indicator. The smaller filter pointed at the evaporator. I blow the old oil out with compressed air and add new oil around 8 ounces. About two cans of r134 cools good. Make sure if replacing the hose assembly to save the old one. Oil usually forms around leaks.

You likely have compressor issues if there's black goo in there (known as "Black Death"). The orifice tube is not designed as a filter for the whole system.

You'll need to flush the entire system out (except the condenser, that should be replaced, as you can't effectively flush it out due to it's serpentine-flow design), replace your compressor, orifice tube and accumulator, and then recharge the system with the proper amounts of oil and R134a.

Yup 4x4 is right it is black death "cancer'. I saw the same problem on my moms 93 Taurus.

I agree. From the way your story goes, I guess the main root for those symptoms is your compressor.
