Since I am dealing with what might be a SC clutch problem, can you try this test for me. Pop the hood, start car, and see if the SC is physically spinning at all with the clutch not engaged at idle. I could not stop it spinning by hand. Careful here. Then turn on the A/C. The SC should kick in and be spinning at pulley speed. From what I see, if you want the SC kicked in then just flip on the A/C. Great video by the way.

Thanks,
Karl
