Hi,
I replaced the serpentine belt 3 months ago to remove the squeaking sound.
Now with AC activated, there is a rattling sound around the tensioner area.
I can see the tensioner vibrate little harder, and the sound appears
if we shut off the AC, car runs fine.
I do not see or feel like it is an idler puller or possibly a water pump, but I could be wrong
any advice is appreciated

A cheap mechanic's stethoscope could be very handy in your case. Mine has always been able to isolate the noisy or worn-out component for me on multiple vehicles over the past decade or so.

Crossing my fingers it is not the '$1000" tensioner.

Could be the A/C compressor clutch.

My '13 does exactly the same as in the video. The noise seems to stop when turning off ac. I haven't had time to get under the car but I'm looking at the possibilities.
