So, I've noticed this odd noise lately in my 2009 3.6L. It may be happening all the time, but I only notice it at a stop while at idle because there isn't engine/road noise to interfere. It's like a cycling noise going on and off, almost like a noisy fan or some plastic on plastic rubbing. I'll here it for a second or two then it goes away for a second or two and that cycle repeats indefinitely. I thought at first it might be the blower fan, but turning that off, on, or different speeds didn't affect anything. Does anyone know what I'm talking about or what this might be?
