2002 Honda Civic - AC Question

I’m having trouble with my 2002 civic AC.

The issue is low pressure. After jumping the low pressure switch, the AC kicked in. When I shut down the car, there was a hiss coming from the blue low pressure line dust cap.

I had some work done on the AC last summer, and I’m assuming that the Schrader valve loosened, or possibly failed (not sure what the chance of that is). When I depress the Schrader valve, there is pressure in the line, just not enough to engage the AC I figure.

Would it make sense to try and tighten the low pressure line Schrader valve, and charge the AC with a kit? Would a Red Tek kit be appropriate?

From what I’ve read, you should charge the AC when the AC is running. In my case, the AC doesn’t run because of the low pressure, so should I jumper the low pressure switch while filling?

I’ve also read that low pressure when the AC is running should be max 40 psi. Is that true for a 2002 civic as well? Is there somewhere that I could confirm the specs? i.e. service manual?

Thanks in advance, I would appreciate any help.
