When i turn on the a/c or the defrost there is a heavy vibration that occurs once the a/c clutch engages. When i unplug the compressor it doesnt vibrate. I was wondering if there is a way to tell if the vibration is coming from the compressor or the pulley clutch? Please help me out it is very annoying Then once i figure that out; how to fix it?

 

I have also notice that when the electrical fan turns on it does that same thing. Does the a/c compressor engage when the electrical fan turns on? or the other way around? (electric fans turns on when the a/c is engaged)

someone help me out
