W124 Centre console lights not working - solution.

[robparker]

If the main instrument cluster back lighting is working, but none of your console lights illuminate (eg window switches, heater control switches etc) then you need to pull out the dash cluster, and on the back of it behind the oil/temp/fuel gauge (pictured) you need to replace that little red diode which is circled, then your lights will work again.

is there a part number for this part?

Rob only thing is they are so hard to find for the W124 model . [ keep well mate ] Trev

No issues with continuity of the red diode/fuse. Still the center console lights (window switches/ power mirror switch & fader) do not light up. All other lights are okay. Anything else to look at?
Would be helpful if there is a schematic of how the lighting is connected for the these switches.

donpmg if fuse is good it will be the pcb board on the cluster thats failed .you night see it if you look close​

 

[donpmg]

I have checked the continuity and there seems to be no abnormality within the cluster pcb. Any diagram on how the wiring and supply works through the cluster to the center console switch illumination?

What you think is a fuse, is a diode,, Rob in the first post told you that ,,i think you need to find a new one If you lucky Rob might have one ..

 

[donpmg]

So even if there is continuity to the instrument cluster illumination lights within the cluster through the red diode, can this being defective cause the center console lights (window switches/ speaker fader switch / power mirror switch) to not work?
The main dash lights are also working with no issues.

[donpmg]

Yes noticed that but did send a message to Rob hoping for an advice.
Any other experts have an insight on this?
