Aircondition

No voltage comes to my compressor relay, system is fully charged, everything works but compressor. Fuse for AC clutch relay is good. I can send power to relay and a.c. runs and cools.
Not clear on what sends voltage to relay can someone help me out?

a wire sends it bro

in all seriousness, go to cruiser54 website, free download the '95 FSM, (correct for '96 A/C), all needed info to diagnose the issue is there

some bedtime reading, fix the problem in the morn

I know the PCM controls the A/C, (but I think its via ground)
