Looking for Guide on how to replace the EL(electro ) Light on W211 Instrument Cluster
My W211 E280 2006 Facelift have issue on the clock side of the instrument cluster. The EL light is not working (I have tried crank the brightness to max). However the speedometer and RPM meter side is working fine.
I have bought the EL light but cannot find any guide on how to replace it. There are plenty video on repairing the instrument cluster however none of it provide the guide on replacing the EL light.
