Where is the AC clutch relay located on 1988 GMC C1500 Sierra small V8. Put on new Ac compressor last year & worked fine all season. This year getting no voltage to clutch switch.

That is the automatic result of most any problem in the system so it needs to be checked thoroughly. Being empty on refrigerant is the most common cause.
The relay is located behind RH side of I/P, on top of plenum
