I converted mine to R-134a last year. It works just as
well as it did with the R-12, but the R-134a requires
more head pressure (high side) to cool as efficiently
as the R-12 did. The only noticable change is that the
radiator fan runs on the second speed more often
because the high pressure switch will trip the second
stage relay more often.

The simplest way I found is to physically feel all of
the hose end connections to see if you can feel any
oil on them. I took my Jetta to a shop, they used an
electronic freon detector to find the leaking
evaporator.

My advice would be to find a competent A/C shop to
check things out for you, one that will explain and
show you what's going on with the system.

Good luck,

Trying to stay cool in Orlando,
