check fuse, and wires in the engine bay. make sure none are rubbed together.

last thing i would check is the switch. they do break over time.
the plugs are in the right spot and the fuses are fine. i understand that the left low beam not working is probably because of loose wires or something simple (since the passenger side still works) but i'm not sure where to start on the high-beam problem, the lights dont turn on but the symbol on the dash won't turn off
