Recently I have had all of the lights associated with 4L go out on my LX470. Before, when I shifted from 4H-N-4L both the center diff lock switch as well as the VSC OFF switch would come on on the dash. I replaced the center diff lock switch on the center diff and now that light works but I still don't have the VSC OFF light coming on. Is there a separate switch that actuates that light that I can troubleshoot? I also have my "D" selector drive indicator light out on the dash but haven't replaced it because it's bright at night, could this have something to do with the other lights on my dash going out? Thanks for the help!
