Why is my 2000 grand am radio light not on?

Mine has gone out as well. GM is not known for their electronics... I have done some research on the subject and I found out that there is a little light bulb behind the display. Apparently you have to take out your stereo, dig around and find the bulb, then replace it. Depending on your technical prowess you may just want to replace the head unit itself. I've found some for around $80 online or you can upgrade to a new head unit from Best Buy for not too much more. I won't look stock but meh... You can get replacement bulbs that size (it's tiny) from Radio Shack. Don't know the size or wattage or whatnot but most of the employees there are well-trained and can at least help you look. Hope this helps!
