do you guys know if the power door lock and power window lock buttons located on the drivers left side (driver door) is supposed to illuminate at night? All the window controls, on this door do light up except this two. They are located side by side (last two control buttons). I'm thinking they share the same bulb and mine blew out. Just wanted to check with 2004 sorento EX-L owners so I could take it back to dealer. thanks
