Alright, double secret probation then.
I had the same issue, and when I charged my a/c (to test if the system even worked) I heard a nice hiss coming from behind the driver side headlight when the car was off. It was leaking right at the AC pressure switch which is right above the accumulator / drier.
FCP Euro has the part for under $10, but was able to order it on amazon for $13 and have it the next day. If you want to search for it they have it labeled as the "Four Seasons 35758 System Mounted Low Cut-Out Pressure Switch". It was a BEAR to remove, and it's MUCH easier to pop up the driver side headlight to get to the fitting. Mine was so corroded (probably original) I had to use locking vice grips to remove, but the new one slid right in... and fixed my A/C leak.
Now to fill up and test again to see if I have any other leaks before doing a full evac and charge.
