hello i have an 87 seville and my dash lights are blank...the fuses are all good. What can be the problem cause before they use to work off and on and my grandfather didn't let no one drive the car up until now that I have my license and he gave it to me..... what can be the problem?

Im not trying to be a smart a s s,but is the knob that activated the lights turned all the way to left?

Well If you are talking about the interior lights, the 87 cadillac seville has no knob and I have it pushed over to Max just about...but unless there is another knob somewhere I don't see than that is not the problem
