Growling from engine

[Howey]

Guys, my car has started a groaning whiney sort of noise this last week from the engine bay...it increases and decreases with the engine speed and totally disappears instantly the moment the A/C is either turned off or put into Economy mode.

I am thinking AC pump pulley bearings about to fail but wondered has anyone had this issue?

sounds like the pump not the pulley:(
