unable to locate a/c freon leak

99 Prizm has had 3 rounds of freon added and keeps loosing it's cool.  Dye has been added and nothing shows up anywhere.  Sniff test has been done and all seems fine there.  High-side and low-side fittings on A/C lines have been replaced and that was no help.  Trying to avoid major dash removal to "look" for the problem.  Mechanic seems very capable and is baffled by this one.  Any ideas?

Crazy problem. Very rare to do those tests and not have the problem reveal itself. I don't think there is an easy solution here and the dash removal may be the only option. You could possibly try another mechanic and let him know the tests that you have already done and see if he is any more capable.
