I have a 2004 Grand Prix GT. I recently replaced the original stereo and window/door lock control panel with OEM replacements due to wear and tear on the originals. Everything works, but for some reason I don't have the orange backlighting on the stereo, A/C panel, or the window/door lock panel anymore. I checked the fuses, but they are all intact. Is there a second fuse box somewhere in the interior? Logically, if it was working before I touched it (it was) and now it's not, the problem probably has something to do with something I handled. But what? Does a wire in the stereo control that backlighting in all three devices? Here's the other weird thing: it all seemed to light up fine when I first connected the replacement stereo. It took a second, but all the buttons eventually lit up with the amber backlight, but then by the time I finished installing the door switches, the backlight was not working anymore.
Any help is much appreciated; I'm selling the car and have an interested buyer looking today, so I want to fix this ASAP. Thanks to all.
