    I have many years of experience of working on freezers and refergerators, so I am aware of the dangers of working on A/C systems. I have a leak, but cannot find it. I charged my system with 2 small cans of R134 with dye in it. In 24 hours, the system was completely flat. I looked for dye residue inside and out. Every connector, joint, seal, vent....nothing. The only trace of dye was inside the low pressure valve, so I know what to look for.

    I found leaks on old R12 systems with soapy water, so I'm new with the dye. Any suggestions?

    Are you using an ultraviolet light to look for the leak? Just making sure, as you won't see the leak without one.
