Default Rattling noise when AC is on

I have a 2004 Dodge Durango ST with 141,000 miles.
When I turned on my AC while I was driving yesterday, I began to hear rattling noise and my truck was running loud. The noise went away after I turned the AC off and truck was running fine afterwards.

Any idea as to what this could be.

Compressor clutch. Or belt tensioner.
