Ok I tried forcing it on in the A/C compressor relay, no dice.
Only thing I can think of at this point is that the compressor is seized up, but that wouldn't mean the clutch wouldn't at least try to engage.
Maybe the clutch is bad?
If I pull the clutch off, how would I identify that?
If the pressure sensors were bad, they would have been over-rode when I bridged the connections in the compressor relay, correct?
