car came from a friend who had a shop look at it last year, they charged it and it lasted less than 24 hours, friend went back, they said
evaporator. removed it, and pressurized with compressed air 125 psi falls to 90 psi in about thirty to forty minutes.
I had ordered a new one ( evaporator ) but it was received damaged, another one is not until tuesday, so in boredom i thought why not, if it's leaking it should bubble right ?
put evaporator ( connected in system ) in 5 gal bucket, no bubbles, but still pressure loss, what else could it be ?
any common places i should pay particular close attention to ?
condenser looks okay for a car with 135 k on it, i'm leaning towards shaft seal ?

well, I found it !!!!!
Can't really see it in the picture, but the bubbles are coming from the high pressure line from the compressor to the condensor
You are one ambitious guy pulling the evaporator so quickly. Last thing I would want to do.
A sniffer or dye test should've caught the discharge leak. Heck, when my '05 DTS was just three years old, the discharge line started leaking. You could see the oily mess even if you were almost legally blind. Credit you for being so thorough though.
Well, since you've got the dash out, now's the time to change out any bad actuators, so scan for any HVAC module codes.
