   I just was messing with an in-op AC compressor on my other van.    There
is a low pressure switch that you can jumper...probably similar on the
Vanagon...dunno,  my Vanagon just has windows, wind-down window that always
work......Anyway, you unplug the switch, which on my other van was near the
condenser (?)  There must be enough refrigerant inside the system... to
trigger that switch or  no current is sent  to the compressor.  If you
unplug the line to the switch and jump across the two terminals with the AC
turned on, you will see your compressor engage..maybe.   That tells you you
may just need more refrigerant..I am told.  Bet you could find it in the
Bently book if you have one.
