Need help figuring out this problem with my air conditioning and I’m trying not to break the bank. My car stopped blowing cold air, I found the compressor was not engaging pressures were high and so I ended up replacing the compressor recharging correctly and it worked for a day then the same thing. Repeated the same exact process two more times with new compressors with the same results. Replaced the expansion valve, and condenser and still no luck. The system holds vacuum (I let sit for 2 days and no change in pressure). I cannot figure out what the issue is! Please help!

When I charged the system each time the low side was around 35 and high side around 150

no was just the condenser

didn’t check if the fan was coming on, right now the compressor won’t engage and low side was around 110 and high side still around 150 I believe.
new compressor from oreilly not reman

That compressor is considered clutch-less ( If memory serves me right) Most likely no power at the compressor or pressure switch.
Gonna have to see if you have power at the compressor, break-out a meter or test light. Electrical gremlins.

Possibly a bad connection that driving vibrations push over the edge.
Could be a bad switch any where from the dash to the pressure sensor, plus if thats a variable compression compressor there's addition switching internally. You said it held a vacuum so in theory the refrigerant level should've have been correct since you said it worked for those couple of days. So a part failed or is no longer connected. Unless you know for sure the compressor was working internally any gauge reading you got really don't indicate much besides the presents of pressure above a vacuum.
Informative video.

With 35/150 you should at least feel some cool air. If the compressor won't even stroke it's probably a control problem. Maybe the wiring is weak somewhere? A shop with TechStream might be able to tell you more about what the system is doing.

With everything being said and the parts replaced already, I'd check to see if the refrigerant pressure switch is working correctly. It's supposed to do exactly that, detect the pressure of the refrigerant, and depending on the readings, send an electrical signal to cycle the compressor on or off. I have a feeling there wasn't anything wrong with the compressor, condenser, or expansion valve. Hopefully, you saved the original compressor because I'd trust it's reliability over some random one from O'Reilly.

I posted this in another tread but it also applies here

Check the condenser to see if it's full of bugs. Without proper airflow the high pressure switch will cut off the compressor because a the condenser can't remove enough heat from the system. The pressure switch for the A/C is like fuses for the electrical system.; you should check to see what may be causing the switch to kick in before replacing it.
