Chris,
The earlier AC' do not make cold air or distribute it as well as the later
units. Was the expansion valve changed? How did you know how much
refrigerant to add? Sight glass? One of the problems with the 134-A is that
folks tend to overcharge them. They should only get 80% the volume of R-12.

Subject: 85 Westy A/C - Advice

Hello all,
My adventurous mom and I just went in on a beautiful 85 Westy that has had a
lot of good work done to it by the Autobahn Society in Georgia. Everything's
awesome on it - especially the remarkable power in the re-headed 1.9 liter
engine. But the AC ain't so cool. It's got the earlier factory rear ac that
fit
entirely in the rear overhead cabinet - different from the larger rear model
in
later westy's.
It's got an R134 conversion and appears to be full of refrigerant with a
brand new compressor. I added maybe 1/3lb of freon in it yesterday til it
woulnd't
take any more (it's now around 33PSI low side at idle) and it just doesnt'
blow very cold - i'd say it's putting out air in the upper 50's to low 60's.
Today in Charleston it was about 88 and humid and it barely kept the van
liveable. Does anyone have one of these units that's been "134'd" and any
experience
on a decrease in cold output because of this refrigerant's lower cooling
ability compared to R12?
I had the later rear model AC in my 134 converted 87 Westy Syncro and that
thing blew plenty cold. Any advice appreciated.
