Mine was fairly simple. I did have a leak about two years ago, not sure where though. This year I finally go off my fat ass 3/4 into this hot summer and decided to do something about it. About 5 months ago I still had the belt on my non working a/c compressor, well take make a long story short the clutch bearing seized. Luckily my wife's uncle is a mechanic at a dodge dealership and he scored me a used compressor and clutch (I won't tell you costs but I'll give you one guess). So I put that on and he took my car in to the dealership and installed oil, dye and freon (once again, I won't tell you costs but I'll give you one more guess). So I am hoping that the old compressor may of had the original leak because I put new o-rings (which is a common leak failure in the LH series cars) on the 2 lines that connect to the compressor. So now it works and if it does leak I will be able to pick that up with the dye he installed, but I should at least get through the summer. Tell me what problems you have with your A/C. I know there is a little switch that is located by that tube next to the radiator that commonly goes south. I know they had problems with the condensors which is under the dash.
