Replacing lights

I have a Delco AM-FM Stereo with Cassette Tape Player and Automatic Tone Control and some lights on the radio buttons are out. Also to the side of the radio, the lights that illuminate the Rear A/C, Rear Heater, and Rear windshield wipers switches also went out. How can I replace the light bulbs?

The radio faceplate illumination lamps are soldered into place, and are not intended to be serviced. However, throwing in the towel would be the easy way out, and one main reason we are here is because many of us won't accept "No" or "it can't be done" for an answer. You can remove the radio, remove the faceplate, and replace the lamps. I have outlined the procedure here:

As for the rear heat, A/C, and rear wiper control illumination, the lamps are harder to find, and the blue silicone covers for them are even harder to locate. The dealer has access to the covers for larger lamps, but not the small ones in those switches. I've had two of them fail in my Astro and have not as of yet found the correct lamp. It's not that I've given up, but that project is simply on hold, along with about 80 others.
