Noises

This is a surprisingly quiet car. My Vibe is atrociously noisy at highway speed by comparison. But there are noises. Noises I notice just because I'm not used to them, and some I'm not familiar with.
While driving, I hear a servo motor making adjustments. Is it the mixer valve in the climate control manifold? The sound bounces around and I could swear it's coming from behind me. There's no servo-type mechanisms back there, is there? Hmm, mysteries.
On my way home today, I realized there was a significant whistle. Wind noise. That's weird. This thing has a 0.25 Cd, right? Shouldn't be whistling. At home I looked at the wipers. They looked like they were all the way down, but I pushed on them gently and they went down further. Maybe they were sticking up into the airflow and causing the whistle. I'll find out tomorrow.
