driver side dash noise

[mtbpath]

Not sure if this has been talked about.
But is this common. A noise coming from the drivers side front dash. sounds like maybe between engine fire wall and inside dash. I've heard about people saying dash fans. but wanted to know if there is an exact problem to what I am experiencing.
mostly heard when accelerating, not hard, but moderate accelerating.
I can't seem to duplicate every time.
thanks all.

I haven't noticed any noises myself. Could you describe it further? Are you saying that is sounds like fans from the in-dash HVAC system?
