AC Clutch? It engages the pulled to the compressor when the AC is on. When off it let's it freewheel so it's not turning the compressor when off..since it wouldn't be off then. Haha it's got an electro magnet in it that sucks the pulley to it when you turn the AC on hence the wires.Can anyone tell me what the hell this thing is and what it does: it's a wheel on the front of the AC Compressor on the other side of the belt. SOMETIMES and i don't know why it does this, but i need to know haha about every 5 seconds this wheel spins for a second and it feels like it pulsates the whole truck as it's running, and it just comes to a complete stop. spins, stops. what is this doing? (this isn't a picture of my engine bay, it's an example online) My truck is a '80 High Sierra 454 with factory A/C that doesn't work at the moment
