Hissing sound

[matrix21]

Hi guys,

I have a strange hissing sound coming from under the dash (midlle, near the steering wheel) when i'm at idle. It goes away when i accelerate or turning the steering wheel...

My car is not turbocharged, so it's not a boost leak...(ES GT 2002 stock)

What is it then ?

Could it be the p/s belt ?

Thanks for your hel

Check you vacuum lines.

Check you vacuum lines.

Even if it's coming from the inside ??

I can't hear it from the outside...even with the hood opened.

That is strange. Not sure then.
