Thanks for your help. I had a slight chirping sound in my blower motor fan and had it replaced last fall. The sound was definitely random and came from under the dash area.

Now, I have a much louder whirring or squealing sound coming from using the fan - whether A/C is on or not is not an issue. I thought it was a radio interference sound because it reminded me of that as the sound got louder as I increased fan speed from 1 to 4. But with the radio off, I still get the sound. After I turn up the fan past 4, no sound. If I have the fan on and kill the car, I will hear the sound like a high pitched squeal or screech for a two or three seconds as it whines down.

Fan runs fine. A/C is fine. Just would like to know what I need to ask about when I take to dealer next week. I don't want to ask for too much because I am sure they will give it to me.
I already replaced the blower motor, but this is louder and not the same sound.

Thanks!

"sounds" like a blower motor bearing or some sort of interference issue around it.
