1993 chevy z71 no power to ac compressor

Should I get power to the compressor clutch by turning the controls on inside the truck?Used a test light and turned the ac on but not getting any power to the compressor.Is there a relay that sends the power if so where would it be located?
Thanks for any information.

Is the system charged? Check for power at the low pressure cut off switch, located on the reciever dryer( silver tank on the firewall passenger side with 2 lines going in it). If you have power there and comp wont run check the charge in the system, if charge is correct replace switch. The switch is on a Schrader valve so you wont loose the charge if you take it off.
