2000 C230 dashboard problems

[rdf63]

I am having problems with the lights for a 2000 C230 Kompressor. The fan (on the left side of the middle dashboard) and rear defroster, both located directly above the radio do not light up when I turn on the lights. Ironically the fan directional, also located above the radio (on the right side of the middle dashboard) does light up. Any advice on what the problem may be.
