Default Re: Radio Dimmer Wiring

>the LCD dimmer back light is not working when the parking/headlights are on. The buttons are being illuminated however,....

I think problem is burnt-out incandescent bulbs (for LCD backlight)
I think the issue becomes widespread after 20+ years, probably because those bulbs are subject to a hotter environment(under LCD, rather than on-board with ventilation surrounding)...

Richpin has video of replacement radio lights for Gen2; following some relevant threads {this a current issue for my 2000, thus my search skewed to Gen3}:
Saturn SL1 Radio and bulbs 1999
2001 Saturn S Radio has no back light
97 SL backlight
