Well, if some on had R-12 sitting around, it will cost several hundred $$ if
you can get R-12. They make direct replacements R-402A or FR-12 which can
be used as a 134a replacement. The entire system will have to be evacuated
and recovered to about 500 microns. Once this is done the replacement
refrigerant can be added. It is not something you can do unless you have
the equipment.

Freon is a brand name. There are several types of
refrigerant out there, home use (R-22), and car use
(R-12, R-134a). R-22 is not compatible with R-12
and R-12 is not compatible with 134a.

You have to use either R-12 or a "substitute" gas.
Most local auto parts stores have these but none of
them work for long.

The best soltion is to convert to 134a, but that
will be expensive.

Within the last month I bought from the original owner a 89 Cherokee. The AC
had required recharging frequently over the years and her mechanic no longer
had r12. I evacuated the systen and put in 2 cans of R134 one containing
conditioner and compatable oil and it's working fine sofar. I can tell where
it's been leaking because there was a oil/dirt build up around a fitting. I've
refilled older r12 systems with r134 a few times on VW's and have found if the
system was sound and just low on refigerant that it would work well.
