i cant see anything My driver information center screen, 99 gp gt, if the sun hits it i can sorta see some of it. The buttons along the side of it still light up with the rest of the cars interior light. Is this just a replaceable fuse? Lightbulb? Or do i need an all new d.i.c?

sounds like like the bulb for the back light is out, ive never replaced one though you will have to take it apart and see.

There'* 3 bulbs in the center, GM Part # 16151234 (pkg of 2) or as an option some guys have used Sylvania 24 LL bulbs.

Pull off the dash trim, release the two tabs and unplug it. Release the 5 tabs holding the faceplate on, then remove 2 screws (Torx #10 iirc) Pull the screen/circuit board forward and down to release the tab at the bottom, and you'll see the three blue bulb sockets on the back. Just twist & pull them out.

Thank u
