Maybe he meant not working?

Just check it with a test light.

That fiber optic light works off of the bulb in the upper right corner of the gauge cluster (either the tach or fuel gauge depending on what you have).

So that is what that wire coming out of the cluster is for. I was wondering about that when I had the cluster out the other night. It wasn't hooked to anything, but I wouldn't have noticed the ash tray not being lit.


That reminds of another question;
does the heater control only have one bulb to light it up? Mine doesn't seem very bright even with a new 168 bulb.

there is only one bulb in the climate unit.

And it's dull on my truck too. Maybe a good place for an led.

Wow, I had no idea about this light. I just got my truck a few weeks ago, so I'll have to do some digging to see if this bulb might be burnt out.
