Newbie here, couple of questions I haven't gotten an answer to.
First off... when I'm driving, the car makes a "humming" sound, specially when I just start driving. Dunno what could be causing this, or whether it's normal or problematic.
Second, at times, when I turn the key, it does nothing. I mean nothing. The switch works ok (turns on radio, AC, lights, the works), but when I turn it full, it won't do any sound, and obviously, not turn the car on. Can't figure out if it's an electrical problem or something within the switch.
Any help is deeply appreciated. Thanks.
