Help me check if my AC compressor is seized....

[Sump]

Apparently my AC compressor was seized up according to a Lexus dealer.

So I removed it planning to replace it, but now I am not so sure it is seized or not...

Is there a way of manually checking? Obviously the clutch turns freely but I was told that the some sort of fail safe method in the clutch is where a pin breaks allowing the clutch to turn freely.

When I do turn it there isn't massive amounts of resistance.
When I turn it there is a suction like noise coming from the holes for the AC lines.
Any oily UV stuff that has dripped out has been very clean and bright green.

So I am not so sure now.

Is there a way of being able to turn the inside if that makes sense?

I worked with an A/C tech for a while and picked up a little bit.

If, when you turn the pulley (where the belt goes round) the pump is turning, (sucking noise from inlet) then i assume the clutch is seized ON, the clutch is electronically controlled, (on when the switch is on/ off when the switch is off)

If you put 12v power +/- on to the terminals of the plug, you should hear the clutch engaging and disengaging.

Hope that helps!

Applying 12v to the compressor did absolutely nothing.

I'm thinking coil.
