Air conditioner losing its power?

[felixc]

Hi,

my legacy 1995 seems to be getting out of R134 coolant. It did not
happen suddenly, but since a couple of years, it looks like the air
conditioner takes more and more time to do its job. After the last
couple of days at 90 degress F, I see that it just can't cool enough.
It still cools air a little, and I still see water dropping under the
car. But after ten years, is it normal that the refrigerant slowly
vanishes away?

(My other Legacy 90, with R12 refrigerant, did not make five years
before the refrigerant system started to leak at every O-ring.)

Stick a good thermometer in the center vent. The temp should be ~35
degrees colder that outside if the charge is good.
