something is making noise from the front right corner under the hood and getting louder, it sounds a lot like a vacuum cleaner and is about that loud. I can't locate it, but it is on when the car is running and will stay on when you park the car and exit, until the lights go off when the car auto locks or you lock it with the remote. I figured it might have come up before but couldn't turn anything up. It's a bit vague, but that's about the best description I can come up with. Any ideas?
