I have an '85 Westy with A/C.  The compressor does not run.  The controls
on the dash seem to be functioning--the fan comes on and changes speeds.
I have not yet put the guages on the system.  There does not appear to be
any lo or hi pressure switches on this system.  (The Bentley is nearly
useless for this unit.)   There is one wire that runs across the top of the
compressor.  I am assuming this is the 12V supply for the compressor
clutch.  The previous owner said it ran, but must be low on freon as it
doesn't cool anymore.  I am guessing a relay or fuse has blown or was
removed?
Is there an obvious place to start for this?  I could put the gauges on and
jump the compressor, but that won't solve the electrical problem I have
now.  Where are the fuses or relays for this particular model?
