Hi folks, new kid here with a question. The car is a 2004 Outback, basic model. Lately I've been getting a horrendous screeching sound from under the hood when I hit passing speed on the highway - 65 to 75 MPH (okay, that's actually cruising speed here in northern NJ). It's not constant, and it's not predictable.
So I look under the hood where I think the sound is coming from - the rear right-hand side near the firewall, and I see this thingie:

Looks exactly like a horn, but it's not THE horn - that's in front of the radiator. It's not part of the alarm system, 'cause I can't get it to make a noise by setting or tripping the alarm.
So what the heck is this thing, and could IT be making that awful screeching sound?
Thanks!
