After replacing both AC and Accessories belts on last Saturday. "AC On" noise is still there. I did try to listen to any noise in front of car with hood open, I could not hear any special noise similar to the one heard inside when driving (accelerating/decelerating). No squeaking sound when AC is ON.
Could it be AC tensioner pulley making noise when AC is ON during acceleration/deceleration ?
Thanks.

Noise/Sound is fixed
I replaced all 2 tensioners (AC & Serp.) along with idler pulley. No more noise/sound from engine bay when AC is ON. It is now back to "new" car sound
