A/C Compressor does not turn on the fan comes on when the A/C button is on?

Compressor does not come on the fan comes on when the A/C button is on. compressor turns on by hand ac fuse in engine fuse box is good and has power. checked gauges and the first picture is with engine on, ac on and knobs open on low/high sides but knobs closed at the gauge. second picture is with knob open at low pressure side gauge cannot find any module for ac using a small auto or the auto pro, cannot see any ac modules or anything to do with HVAC. These are only codes it has. Car has few aftermarket stuff like a cold intake maybe but nothing else. I removed the relay and switched it with another same thing. I hear it click when it goes in. Which sides do i jump to see if it kicks on
