The previously described workings of the AC
system are correct.

Low and medium speed dont result in an
A/C compressor shutdown.. only when the 
fan hits 'high' speed does it get muggy.

Just had the whole system on my syncro
R&R'ed (new dryer, compressor and expansion
valve.. what a beeotch!) flushed the system out 
really really well, then re-upped with the expensive
R-12

Stress testing time, the past few weeks in 
phx it has been 105 to 115  UUUUGH!  

I notice (compared to last year) that the compressor
cycles on/off more (probably because I have freon 
now!.. last year, I was down a bit I'm sure!?)  and 
more heat is being dumped up front which in turn
drives coolant temps up.

Radiator, fan etc (entire cooling system) was R&R'ed
last year when the new engine went in as well.

So.. what does that tell you..  I have essentially 
(as *new* as you can get it without replacing the
condensor or evaporator) a new A/C system, and 
a *new* cooling system still running r-12!

the things just dont work that well in 110 degree F
heat!  

if its any consolation, the EV 2002 MV Weekender
gets warm in the 'back' and the front a/c/ has a hard
time cooling the entire van as well.

So, pick your poision  kids stay cooler in the syncro
westy, the front passengers stay cooler in the eurovan.

90 syncro westy
mesa, az

ps  believe me.. either van with A/C is still more comfortable
    than without.  Drove the westy one day 111 without A/C
   uuuugh!  it sucked big time.. worse than when the compressor
   kicks off!
