Working on a 14 year old A/C system can be full of surprises.
The 160$ you mention isn't a lot of money for a fix but in reality I've
removed about five A/C systems from Vanagons and every one had at least one
pinched O ring.
If I were going to have the work done I'd replace all the O rings,
compressor oil, flush the system, install a new receiver/dryer, be sure the
suction valve is compatible with 134r and go ahead and install the 134r just
to get it out of the way.
One thing for sure .......... With the 134r there is very little possibility
you'll ever freeze up the evaporator.

The evaporator can freeze up even in warm temps if the fan speed is low
or the evaporator is clogged. The real problem since there is no low
pressure protection on the low pressure side is the possibility of
liquid refrigerant returning to the compressor. This can damage the
compressor.

Subject: AC Thermostat
After trouble-shooting my non-cold AC, my mechanic friend determined the
AC
thermostat (in left-rear pillar housing) to be bad. The part costs
$160,
which doesn't seem so bad in comparison to a new compressor and/or R12.
But
my friend suggested that I just bypass the t-stat for now.
He explained that the t-stat functions to protect the condenser from
freezing if it gets too cold, but that this wasn't very likely to
happen.
Is this bad wisdom? I'm sure the t-stat is there for good reason, but
if
I'm only running the AC in 80+ temps, is freezing actually an issue?
Thanks,
James V
