E350 Bluetec
Illumination lights not coming on

Hello, I have a 2012 e350 bluetec and I have a problem with the illumination lighting for the console (radio and door buttons). Also, the buttons on the dash doesn’t light up as well. At night I can’t see anything when I try to select mode for air flow or radio controls, because the buttons lighting not showing. I’ve checked fuses for illumination and ambient and they all seem to be good. Can someone point me in the direction I need to go for this? PS: yes I did go into the settings menu and made sure my backdrop lighting (dimmer) was up all the way and made sure lights were on.

Hi Chas.. Maybe this will help.. It seems like you've taken some initial steps to troubleshoot the issue with the illumination lighting in your E350 Bluetec. Beyond checking the fuses and ensuring the settings are correct, here are a few additional steps you might consider:

Check for Wiring Issues: Examine the wiring and connectors related to the console and dash buttons. Look for any loose connections or damaged wiring that might be affecting the power supply to the backlighting.

Scan for Fault Codes: Sometimes, certain issues might not trigger dashboard warning lights but could still be logged in the vehicle's control modules. Using a diagnostic scanner, such as the Youcanic scanner, can help read fault codes from all the control modules in the vehicle, providing a better idea of any underlying electrical issues.

Professional Assistance: If you're unable to identify the problem after these checks, consider seeking help from a certified mechanic or an automotive electrician. They have the necessary expertise and tools to diagnose electrical problems accurately.

Since you've already performed some checks, considering these additional steps might help you further pinpoint the cause of the illumination problem in your vehicle.
