Dark Radio

On my way home tonight part of my radio's buttons went dark. I have a 1999
Silverado with a Delco AM/FM CD player. Is it difficult to replace bulbs in
the radio? And are there bulbs in the radio or is there LED's or something
else in there?

Thanks Brian

Is the display completly out or is it just dim? I had the dimming problem on my mustang, turned out to be a ground.

It's partially dimmed out. That's why I think there must be either bulbs or LEDs in there.

Yes there are backlights behind your buttons ... Depending on your soldering skills this can be done in just a few minutes

Ok heres the rest of my reply ....

There should be a blue covering over them or maybe even a clear lens. My suggestion is to change all of them at once since you already have it apart. Oh and BTW use a sharpie to mark all of your screws and bulbs location when removing them. If any buttons are scratched change them as well (be sure to get the right color coded buttons) spray your CD mechanism out with compressed air to insure reliability....There are a few tricks to make the replacement a little easier just let me know if you need more guidance.

You may be able to find them cheaper .. but at least this will get you in the right direction..
