A weird thing happened while I was stopped at a traffic light. I happened to take a look at my Instrument Panel and observed that the Tachometer and Speedometer needles started bouncing around at the same exact time. This happened for a quick second then the needles went went right back to point Zero. As I resumed driving the guages operated like this encounter never occured. About fifteen minutes later I observed that the right low beam was not operating. I then turned the light switch off for a quick second, and when I turned the switch back on the light came back on.
What could be happening? Is the OBC defective? Can I perform a test on the OBC to make sure that this is the problem? Can I have the original board fixed or do I have to purchase a new or refurbished one? Where can I purchase one? Will I be able to install the OBC myself? Any information that can be provided will be appreciated!!!
