Dash lighting for Therm Messed up?

I was driving at night and adjusting the temp when i realized that the 2 levers for adjusting the cabin Temp and Fan Speed, their light wasnt on. Like the little slit of see through plastic wasnt lit. Am i just going crazy and never realized that they were never lit...or should they be lit?

There are no other dash lights out...so how do i fix this?!

im not sure if the lack of replys is, thats a stupid question or no one understands what the hell you just said man..

Umm, I dont think the lever itself is ever supposed to light up, if you are talking about the white part.

However, if you are talking about the panel itsself, I am unsure how to take it apart, but need to do it someday, cause some of mine no longer lights up.

Yea, im talking about the actual levers that let you select the SPeed of the fan, and how hot or cold u want it. The therm panal itself lights up, but im talking about the actual lever. Just wanted to double check
