An interesting issue. My 06 RT AC LCD backlight is out. Everything works fine but the 4 bulbs that backlight it are out. I just replaced them so they should be good. Simultaneously the interior overhead front right side light is out. Are these connected in some way? I will exchange bulbs tomorrow with the left side and see if it is the bulb. Anyway the backlight seemed to be intermittent last week and now its out. As with LCD, I can see it in the daytime but not night. Help.
Could this be a battery issue? I have seen reference to that sort of thing.
Thanks. I will check that out. In the meantime, I bought a LED upgrade kit for my interior lights. Killing 2 birds with one stone maybe. Will check it out.
