Last week I bought a 2003 LS 430 and have read the manual. My dome light will not go on when I open any door. The switch is set to "Doors" and will go on when I select on. The ring around the ignition key does not light up either but the footwell and mirror lights do light up. I searched the forum but could not find a solution.
