Climate Control lighting question, Regarding the buttons that tell you which vents the air is blowing out Options

[GriffGirl]

This is totally a nitpicky thing but it's something that really bugs me about my car. You know the little buttons that you push to control which vents the air blows from? Mine don't light up all the way - meaning, the little green rectangles light up to indicate which button has been selected, (orange for the defrost, etc) but the little icon below it doesn't light up. All the other buttons light up completely, green squares, icons and all. It's just that top row that doesn't light up.

So before I go and pull the entire CC out I thought I'd ask - is there actually a bulb for that part, or does mine just not light up? I've seen some pix on here where other people's light up, and it drives me crazy that mine doesn't. Am I just SOL?
