If an AC is icing up, it is usually due to too little refrigerant. The
low pressure switches on our Vanagons should prevent that from occurring.

Just for clarification ... the older Vanagons with dealer or port of
entry installed airconditioning don't have the low pressure cut-out
switches unless they were added later.  Neither my '84 7 passenger nor
my '85 Westy have low pressure cut-out switches.  That means that my
compressors will run even when there is NO refrigerant charge, which is
a bad thing, so I have to be mindful and careful of such a situation.
