I bought this car about 2.5 months ago and the hi-beams didn't work. I have changed the fuses and that didn't fix it. Just been living with low-beams only. The car had been sitting up for a while. Since I've been using it regularly, Some of the components that didn't work when I got the car have began to spring back to life. For example: about a week ago, for no apparent reason, the "lights out" warning on the dash began to flicker and now stays on whenever the lights are on. I wasn't aware there was such a system until the flicker, and I checked the owner's manual; but it now seems to be working. Can a defect in this system cause the hi-bean problem? Where are the components and how could I check it?
