my first test would be to replace the O rings and since these are cheap and then add dye to the system along with dried air from a compressor to 140 lbs. and wait. Check for leaks then flush the system!  Does it sound logical to you that someone would spend about $900 on a newer compressor and more on related retrofit service costing upwards of $1000 easily and letting it go?
These cars have had old evaporators fail and this requires removal of the dash to replace which could be one reason. I hope someone just got lazy here, but neglect is just as bad.

Knightrider, try keeping in mind that the person you are claiming to try to help is not in Arizona... thus YOUR air is not at issue...
Who suggests flushing the system with it together ?
You can't get air from a compressor as dry as you need to do this stuff...
No one that I trust says to put dye into the system... do a search... that is why I go with the nitrogen and R22..
Your stance on the evap condition and danger does not match the statistics here on the board.
