Where is it? Does anyone know where I can locate the a/c cut relay on
my 1993 Legacy?

Thanks!

What is the problem you are trying to fix?
There may be a relay that controls the compressor clutch, but there
are also pressure cutout switches that protect the compressor from low
or high system pressure and will open the clutch circuit if the
pressure goes out of the acceptable range. The ECU can also control
the compressor based on temperature and throttle position.

I have already checked the pressure switch which is supplying the trip
voltage to an a/c relay. But, from that relay, power goes through
another relay called the a/c cut relay before getting to the
compressor.

Problem is my compressor clutch won't engage. Thanks for the reply.

ok. So I just forced my pressure switch into the two proper positions
(disconnecting the wire bundle and using a jumper wire) and the a/c
started working. I then reconnected the pressure switch wire bundle to
the system and the a/c continues to work like a champ. Weird. Any
explanations? Did I just permanently fix it?

Maybe the connections to that switch were dirty or loose. It might be
a good idea to put gauges on it and see what the pressures really are.
