Why won't my AC send signal to the AC Compressor?

Testo:

== 2001 Chevy Blazer LT 4WD V6 4.3L ==
 
EDIT3: Since I replaced the switch, I’m led to believe that the only other things it could be are either the AC accumulator or the HVAC actuator. The actuator failing is a common issue with this type of car according to online resources, however, that is the more expensive of the two options. I may have to replace the accumulator to see if that works since it only costs $30. If there are any more suggestions or ways to properly diagnose, I’ll gladly try.
 
EDIT2: I replaced the low pressure switch and it still hasn’t fixed the issue.
 
EDIT: I just [https://www.youtube.com/watch?v=GA_BNOEOKNY|found a video where someone also bypasses the relay]. This is exactly what I did, and this gentlemen seems to be having the same exact issue.
 
=== SUMMARY: ===
 
Hello. So I went to recharge the AC in my vehicle and noticed that the AC clutch wasn’t spinning at all. I did some troubleshooting, and I now think it has something to do with the computer in my car.
 
=== Things I’ve Tried: ===
 
I checked every fuse in the car. Replaced one for my cigarette lighter, and all the rest are fine.
 
In the engine fuse box, there’s a AC fuse and a relay. The fuse is good, and I used a multi-meter and a 12v battery to test the relay, but just in case, I also swapped relays with the horn to make sure they both work. (They do).
 
Lastly I used a paperclip to bypass the relay on the fuse box, and the clutch started, which leads me to believe that the relay is not being triggered when I tell the car to turn on the AC.
 
=== Things I’ve Ruled Out: ===
 
* The AC Compressor/Clutch
* The Fuses
* The Fusebox
 
=== Conclusion: ===
 
I’m not sure what else is left to try, but it’s going to start getting hot soon, and I’d really like to have my AC working.
