AC no cold air

My AC suddenly stopped working. Initially it blows cold air on the passenger side and hot on drivers side. Today i had it regassed then all the vents are now not blowing any cold air. Fuses are confirmed ok, compressor is kicking in. The tech concluded that the compressor is 99% faulty because he's saying that even when he push the gas pedal, the high pressure is barely moving. I dont understand that hehe..

Im researching and read about the heater/water control valve. I'm not sure if that's the culprit or its really the compressor. I just dont want to spend money on replacing the compressor which is expensive, and turned out to be a cheaper part's fault.

Or would it be the Final Stage Resistor?

TIA!

If no airflow then its FSR - if no high pressure when AC running then yes most likely compressor has failed
