How much dye have you put in the system? I have never really been a fan of the a/c dye since the 70's after finding out that the dye will plug an a/c system to almost being unusable ever again, without replacement of almost every part except the compressor and condenser. I have seen the dye look almost like an ICEE drink, it had turned to slush in the evaporator, expansion valve and all of the low-side hoses. I had to replace almost every component to finally get it to work at all. The first thing that concerns me is that you state, "injecting lots of dye" first off I believe that the rec/drier is probably now clogged from all of the dye. I have not used any of the dye compounds since then, as they do not act or have the same properties of freon or the R134A. The dye does not go through the liquid to gas stages as freon does. I have seen many a/c systems rendered useless because of the dye. I would flush the entire system, replace the receiver dryer, either clean or replace the expansion valve, evaporator core. Totally drain the compressor, flush and replace all of the oil for the entire system, flush the condenser, flush and clean all hoses. After all this is done. then I would pull a very long evacuation of the clean, newly oiled, freshly sealed system. Then charge with the correct amount of the R134A and hopefully it will be a vast improvement from even the first time when you had it converted. Just my $0.02 Good luck!
