Well, watch this at 1:07:

and this at 1:57

That is exactly the case with my RAM that has perfect AC and same on niece's RX300. I just went and tried. The outside clutch is splined to the compressor shaft and spins compressor. When magnet in the clutch engages, it slides back, towards compressor, and locks pulley to the shaft. If comp is not seized, clutch spins by hand - but it's spinning the compressor innards same time..

So this is what I am trying to understand.
1. I have seized comp
2. a year ago, vehicle had serpentine belt replaced (could be related, as when comp seizes, it can rip the belt or burn it)
3. I do have low low line pressure, what prevents AC clutch from engaging
4. clutch apparently works, when I did IBDM self diagnostic. You can hear it click.
5. AC light comes up, as it should, does not blink, there is no AC codes.
So if I have a seized comp, what exactly was done to the AC system, to ensure, that clutch does not engage with the engine running? Say someone jumps the clutch to refill the system and rips the serpentine again? Certainly, I am going to replace the comp, recharge the system, but if clutch is disabled somehow else, don't want to be disappointed. Did they simply let freon out of the system, so that switch prevents clutch from function?

I sure could take comp apart and revive it. Done it before. But, for a $200 new one - should I? I'll prolly take it apart anyway, out of curiosity, but to repair and reuse something that broke rather fast - meh.
