A/C compressor question.

Thanks, yes I only can check the suction with my gauge. I can't recall right now the pressures, but the higher the RPM, the less pressure. Actually drops rapidly, which makes me think the compressor is shot. I replaced the clutch at the end of last summer. It is the factory unit, so a new one is in order.
I will replace the drier, but should the txv be changed again too?
Thanks, Paul
