The driver's side vanity light (the one above the sun visor) has been out for a while. The passenger vanity light started flickering about a week ago and then totally went dead 2 days ago. I bought new bulbs for both, thinking that may have been the problem. But after installing the bulbs tonight, both vanity lights are still out.

Does anyone know what the problem could be? I'm assuming it's in the wiring somewhere, but I don't even really know where to check, or what to check for. Any help would be appreciated.

I know vanity lights are a small thing, but I like to keep everything working properly on my baby!
