did you test the resistance of the clutch magnet coil - wait - umm does this one actually use a compressor clutch?

My W210 compressor clutch fried because of exessive air gap which then caused chattering and eventual overheating of the clutch. - In that case the coil windings were showing open circuit and everything tested good including the voltage test for the compressor clutch wire.

I had to reset the klima control unit in order to get the compressor to run otherwise it gets locked in error.
