No power to a/c compressor

No power to a/c compressor
I have a 1991 camaro 5.7 TPI. My a/c compressor doesn't have any power. I checked both the connections with a voltmeter and both were 0V. I checked the a/c fuse and it is fine. One thing that I think might be the cause is I wired both my radiator fans together so they both run the temperature switch, so the a/c doesn't have to be on for both to run. But to do this I had to cut the wire from the a/c radiator fan relay. Does that relay have to be hooked up completely for the a/c to work or is it just a fan relay?

Make sure your GAGES fuse is good.
Make sure your PRESSURE CYCLING SWITCH is good.
Check for AC relay closing.
If it doesn’t close make sure the ECM is grounding pin F1.
If it closes you need 12 volts on pin A.
If you have 12 volts on pin A of the AC relay the compressor clutch should actuate.
Happy Racing!

Fog lights are not driving lights. They look dorky. Turn em off slow pokes.
How bout those dorks too scared to drive without headlights on in the daytime!
