See if you have continuity across the clutch windings.

I'd LOVE to test the continuity but it'll have to wait until the morning.It would REALLY be easy if there was an associated fuse for the sucker but I can't find it!!! Probably controlled by some computer somwhere.
I'm aware of the thermal fuse. From what I've read in my copy of WIS, it seems to indicate that a seized compressor would generate enough friction to set it off.
This thing is slipping ever SO slightly. I fear with the new engine fan clutch I installed a week ago that the underhood temps have been reduced to the point where this tiny amount of slippage won't melt the thermal fuse! I can rotate the clutch easily by hand so I doubt the compressor's seized.
I'm just curious as to why a compressor clutch would fail in this manner? Maybe a return spring is broken?
Would you happen to know if it's possible to replace just the clutch on this beast without possibly removing the refrigerant lines? Clutch is about $150 versus $600 for the compressor. Only thing holding me back in figuring out how I would hold the compressor shaft still to remove/install the clutch. WIS doesn't detail the procedure.
