On my 1998 grand am, The clock on the radio dosent light up, you cant see it, all other lights on the radio work except the clock. Any ideas?????I checked fuses, could it be a bulb or something?

It is a bulb that comes loose, It's happend to me and tons of other ppl. it is a shitty radio they put in there and we should give them shit for it. I had to pull my radio out take it apart and resolder the connection and still it kept coming loose, so i said to hell with it and bought a hype aftermarket radio and now i've added a few things and have a killer system in my car.
