2004 Radio Lights

I have an '04 Trailblazer. Had it for almost a year. A few of the buttons on the radio (specifically: Seek/Scan, 1, 2, and 3) haven't worked since I bought it (in the daylight obviously). But it's only these 4 buttons. All others work. I'll be pulling out the radio this week to add an iPod adapter. What can I look for as the culprit? A specific wire in the the harness? Possibly a fuse located elsewhere?

Thanks!

i'm having the same problem with mine. (its a 6 cd changer). first those went out, then the lights on the stereo for the radio control went out, but the functions still work. anybody have any ideas? also, how are you installing the ipod adapter? i would like to know becuase i have an ipod and i want to install an adapter as well, but don't know how to or which adapter to install. thanks!

I'll let you know later this week the adapter just came in today. I'm going to try and harness my inner tomboy and install it myself.

I got this one from Crutchfield. Peripheral iPod GM Interface Kit (http://www.crutchfield.com/S-yC9UyhAzPlG/App/Product/Item/Main.aspx?i=541ISGM73)

I had the same problem with my '05 TB the lights on the radio starting going out on the volume knob and the 1 and 2 buttons. Luckily it was still in warranty and the dealer replaced the entire radio. They said it was the lights inside the radio and they dont fix them they just replace the radio. Recently I am now out of warranty and now I have to replace a few of the steering wheel buttons as those lights have now burnt out as well.
