Whatz good everybody I got a 2004 durango with the rear ac unit and a few weeks ago I noticed my ac wasn't blowing cold like it use to. So I got a can of freon with the dye and put it in let it run and look around to see where the leak was coming from and saw that right where the lines connect to the rear unit it was cover in dye, didn't even need a black light to see that it was so much dye there. What I want to know is if anybody else has ran into to this problem and if is just an o-ring that is just bad or if it is the expansion valve or evarporator core that is leaking?
