After radio swap my clock numbers disappeared! Bulb is good.

After radio swap my dash clock numbers disappeared! Bulb is good.

Has anyone else in an 89 SHO experienced this? I swapped my headunit for an aftermarket unit and then the numbers on my clock disappeared.

1. This happened after the radio swap.
2. The fuse is good.
3. The bulb is good. You can see the green backlight on at night.
4. I went to the salvage yard and bought an entire replacement clock and it had the same problem. Green backlight with no numbers.

Any idea's?

I solved this riddle.

I didn't realize there were TWO fuses. One for the light and another one for the clock time. When I said the fuse was good it was because I checked the fuse that pertains to the clock light itself. The fuse related to the clock time itself was blown.
