My family recently got back from two weeks in Hawaii where, among lots of other things, we saw lots of Vanagons.  But now that I'm back, I want to take care of some problems with my 90 Multivan.  The A/C is not blowing cold.  It was converted to 134-a in Feb. 2002 so I think it might need more refrigerant.  I have the refrigerant and a gauge but where do I hook up?  It seems that the readily available connector at the top of the engine compartment is on the "high" side.  Am I wrong?  Where is the low side connector?  

Also, if it's not refrigerant, what are the likely problem areas?  The compressor doesn't seem to be coming on.  What and where should I check?  Thanks.  I tried to search the archives with nil results.
