Whining Noise - What is it?

Hey Guys!

On my 04 D2 theres is a apparent whining noise.

The whining noise is the loudest when
- AC Is On at the lowest blower speed
- When breaking hardest

The whining noise goes away when
- AC is Off
or
- When given gas

The whining noise lessens
- Higher blower speeds

Do you guys no what this could be?
I figure it has to do with the AC some how, quite confused on why its louder when breaking hard and when the AC is on the LOWEST setting.

Thanks Guys

So how mechanical are you and what have you checked so far?????
Have you inspected your belt yet along with all the pulleys and bearings?

I'm pretty mechanical, not a pro by far though.
I haven't checked anything yet, not very experienced with these type of issues.

I just had a new tensioner pulley put on, everything looked good do you think thats the issue?

Take your belt off, if the noise goes away then start checking each idler pulley as well as the alternator, a/c and p/s pulleys.
