To anyone out there that knows about Volvo's i have a couple of things i am concerned about, one is that my front left wheel has a humming coming from that area while driving depending on the road and how the steering wheel is turned. What might be causing this and what might it cost to fix in utah. also the second thing is that the front left blinker just kinda randomly goes out and then comes back on, almost whenever it pleases (or so it seems) any thought as to this one?
