W140 Dash Light Replacement (Not instrument cluster)

[dproudfo]

Hey everyone,

I have a '94 S500 Coupe and the center dash back lighting for the vent adjustment wheels has gone out. What is the process for accessing these bulbs? I'm assuming it's fiber optic but I'm not sure where the actual bulbs are located. I've searched the forum and the only bulb replacement posts that I can come up with pertain only to the instrument cluster, not the dash. Any help would be much appreciated. Thanks again!!
