I got the lights fixed! I ended up removing the center console and taking the WSE unit out. I opened it up and cleaned all the dust and debris out - then sealed it up and it works like new. Even the letters themselves light up. I didn't realize that *all* the lights were not functioning before.

As for the glovebox / rear ash tray light - it had fallen out of the metal clip that holds it in place and (I assume) the bulb had blown. I replaced it and now it works great.

I hope that helps anyone that's having a similar problem. I have some pics of the inside of the WSE unit if anyone wants/needs them.
