Solenoid problem in A/C system

I'm want to ask you some help in repair conditioning systems in model s.
So we have a car with broken air conditioner and alert FanRelaySolenoidOS.
We checked all fuses and relays. We replaced compresor and pressure sensor, but alert still present.
We see in CAN so compresor isn't start. And we see the pressure in system. Can you tell me what we can do more? Where that solenoid can be find?
Thank you.
