04 Cadillac DeVille

Has anyone else that owns a 04 Cadillac DeVille had this problem? if so what did you do to fix? two days ago I went out and started the car so it can warm up cause it was a lil nippy that morning and I noticed that the climate control display was blank no digital readout but the funny thing is that the controls still work I can turn heat and AC on fan high or low ect I checked fuses there good is there something else that that I'm missing
