When you say your interior dash lights?? Are you talking about brightness or all the symbols lighting up? Alot of members had the "multi-function" switch for your head lights go bad. In my case, thats what fixed mine. I would be driving down the road, I would notice my head lights would flicker, my nav unit would go brighter and dimmer. Purchased a replacement part from the dealer and havn't had the problem since. Other problems members have had was the ignition switch. You would notice all the symbols on the dash light up if that was bad.
