Does someone know how to replace the bulb for the temperature wheel (left side) and fan speed numbers? I have replaced the bulb behind the knob for fan speed, by simple pulling off the knob. But this one only seems to light up the arrow and fan symbol on the knob itself.

 

No one that has any idea? I know most of the w140īs were delivered with the digital climate control, but perhaps someone has experience from a w124, that looks similiar to this?

 

Figured it out, replacement of these bulbs require removing the whole wooden facia, ash tray etc. Replaced bulbs on both sides, to be sure that I donīt need to redo the whole procedure all over again any time soon.
