Hello, I am a new member and this is my first Mercedes Benz. So apologizing ahead of time if this is the wrong forum.🙏 I tried to look for E350 forum and there were several different E350 forums so I wasn't sure which one to post on (each E350 forum was followed by a few letters, not sure what the letters were referencing?). Perhaps someone can be kind enough to point me in the right direction.
I have a 2011 E350 Cabriolet. The other day, I experimented with the passenger seat lumbar support as my wife was driving. Each of the lumbar support buttons worked fine. Then all of a sudden, the passenger seat lumbar support buttons all stopped working. However all other seat adjustment buttons worked just not the lumbar support buttons. I assumed it was a blown fuse.
Oddly enough, the next morning the passenger seat lumbar buttons started working (for good measure I tested the driver's seat lumbar support buttons and they also worked fine). However, when driving at night, I noticed that the lumbar support buttons were no longer illuminated. Not sure if it was just my imagination but I could swear they used to light up at night.
The questions I have are:
1) First off, are the lumbar support buttons supposed to illuminate?
2) Doing a little research, I see that there are several seat fuses (I think 6; a few under the hood, a few in the interior drivers side, and a few in the trunk right hand side near the spare tire).
Are there any specific seat fuses that control the lumbar seat lights?
PS - I tried calling the dealer but they were of no help.
