> Highly unlikely. Try a diffrent technician/shop.

Actually, the first attempt was the dealership. They gave me the stock
answer: "Since we can't see the leak-dye anywhere, it must be in the
evaporator core. $1400 please."

I'm really stuck as to what to do here. I'm trying to sell this car, and I
just don't think that dumping another $1400 into it is something to do given
my luck with cars: after the a-core is replaced someone will discover
something else cheap and easy to get to that was the problem all along.

It's the way it works with me.
