hello , my 2010 E350's climate control switches and heated seat switches do not light up and are not working. The AC electric fans are running full blast.
it seems there might be a common power feed issue but Im in a wheelchair and cant easily diagnose this problem Does anyone have any ideas or an electrical schematic to help with this issue.


thank you for your time.

Michael

My 2013 W212 has the fuse numbers, amperage, and location on printed list in the tool kit under the trunk floor. I would check for multiple blown fuses, or relays before any further diagnosis. Good luck!
