chirping noise

[dcx5]

when the x5 is cold, if i turn the heater on there's a chirping noise coming from inside the dashboard/fan. has anyone else seen this or know what the problem is?

I sometimes get that noise also but not when I turn on my heater, when I start the ignition it makes that noise real loud and after a minute of driving it goes away..I have no idea what is causing it to chirp but I'm taking my car in tommorow so they'll figure it out

i think it comes from the intake adjuster...
