Yep, we have a V6 '02 Camry, and every once in a while we hear a sound like a slide whistle. The tone is ascending.
We hear this in the cabin, and it doesn't sound like it is coming from anywhere in particular. We only hear it if the AC or the fan is on, but it doesn't sound mechanical, not like a belt or something scraping. It is infrequent. Anyone have a guess?
