I have a 2000 RX and have noticed something about my dome lights. Occassionally, and for no reason that I can determine, they just don't work. When I open the doors they don't come on and when I flip the switch on the light - nothing either. They also don't come on when I unlock the doors with the remote like they normally do. Then after a day or so, everything back to normal. This has happened to me twice in the last 4 weeks. Any ideas?
