Dash Control Unit does not light up HELP!

The screen that shows the air flow and temp setting is blank. I have checked the fuses and they are fine.

Does any one know of a way to trouble shoot this screen. Or where I can find a replacement.

It is a 1991 3000GT DOHC 5speed. 119,000 miles.

Thanks for your help!
P.S. I think this is called the Dash Control unit.

Interesting, unless your a TT model you should not have climate control.

not true i dont have a TT and i do have climate control as well as many other options u wouldnt suspect such as all the seat settings and stuff like that..but yeah i kinda have a similar problem except i only lose those lights when i turn on my headlights or parking lights lol..kinda weird but im over it really

SL's had Digital Climate Control up until 93. They lost the option in 94.
