Yes, I understood that. It does the same thing no matter what wiper
speed. I'm quite sure it's the driver side, as I ran the wipers while
standing outside of the car by the driver side, then walked around to the
passenger side of the windshield. Yes, the car was parked. It does
sound as if it is coming from the far end of the wiper: the end that sweeps
the large arc. I can't be sure about that, but next time it rains I'll
listen more carefully. Can't gather too much data, ya know?

I'll try your suggestions -- thank you!
