Dear "another",

Good p.m. and hope you're well. The dye evidences a desire to spot any leaks, not necessarily that there were actually leaks due to holes in key components. For example, a loose fitting could have led to refrigerant loss. The dye migth have showed that a fitting was loose. Once that was put right, the system was tight.

Your vacuum test, though, likely means there are some pinholes. I'd target the evaporator (under the dash). Put a black light inside the footwells, and see if there's any sign of fluorescent stains (dye-loaded aircon lubricant). Check also the evaporator. Sometime stones can punch small holes in it.

Hope this starts you moving towards cool.

Yours faithfully,

spook
