Hi there...

My 2003 FWD RDV is starting to make similar whistle noise as well. So far, I think its internal Heater fan is going or perhaps its AC clutch pully is going. If wondering, my RDV only makes a noise when its heater / cooling switch is NOT on zero. When on "0" setting, no sound at all. Thus, why I think its the AC clutch - like the worn out AC clutch sound in our previous 2000 Sunfire (just before its AC clutch pulley was replaced). For now, we'll leave it - until its sound gets much louder (and easier to identify its location).

Hope this helps - some how....
