How do you fix temp display on climate control of 1998 Buick Ultra that is not working but the temp controls still work?

Answer:
I found the display on my brothers Buick not working. i disassembled the control panel. inside there are three resistors that had bad solder joints on them and had started to burn the circuit board. i cleaned them up and soldered them. display came back on and the fan controls now work.
