Assuming a reasonable refrigerant charge level there is a sight glass in the rcver/dryer that can be used to determine the compressor is operational. Clean the sign glass well and keep a good eye on it while someone operates the A/C system, turning compressor clutch on....then off.
Shortly after the compressor clutch engages you should see a transition from gas (NOTHING!) to bubbles (plain to see) to liquid refrigerant, NOTHING again. Reverse for compressor clutch off.
If you do not see this transition that might also mean a low, TO LOW, refrigerant level and you shouldn't be running teh compressor at all.
