Hey all! Need some help from someone more experienced with AC work. I have a refrigerant leak that I cannot find. It leaks out every 12-24 hours, so I've been living without air for the most part. I've put UV dye in; couldn't find anything. Put a double shot of dye in; couldn't find anything. Hoping it were a small leak since I couldn't find it with dye, I tried a refill with stop leak. No change, didn't even seem to slow it down much if any. I replaced the high and low side valves, no change. I purchased a sniffer, put a charge in, and I've been going over it for the past hour. Every line, every joint, all over the condenser, around the compressor, in the vents, under the dash, everywhere. The system lost about 5psi while I was searching with the sniffer but I cannot for the life of me find the leak. I did confirm the sniffer works with a controlled leak out of my gauge set.
One piece is that after I have charged the system, if I walk by the passengers side of the truck in the evening I can smell the refrigerant so I expect the leak is somewhere in the engine bay, not under the dash. I am trying to avoid replacing everything just to start fresh, but that is nearly the point I have reached. Any input on better testing methodologies or likely spots to check I may have missed, I would be greatly appreciative.
