Door lights - stopped working is there a fuse
Hello, greetings to All Members
ML350 (W166) 2013. My door lights (which should turn on automatically when the doors are opened) have stopped working on both sides. At the same time, the tailgate-closing switch light also stopped illuminating, although the switch itself still works and closes the tailgate normally. I removed the lights and checked the bulbs, and they are fine. Using a multimeter, I discovered that there is no voltage reaching the lights. I’ve read that in newer models these lights can be disabled through the settings menu, but my 2013 model doesn’t have that option. So my question is: Is there a separate fuse that supplies power to these door lights? Everything else in the car works normally. If such a fuse exists, where can I find it? I don’t have a fuse diagram.
Any advice or knowledge would be greatly appreciated. Thank you.

this is the ML63-specific forum. you will have better luck in the non-AMG forum for the W166. I would suggest posting there.
The fuse diagrams for the W166 are easily available online. if you want to send me a DM with your email address, I can send them to you

Yes, there is a fuse for those lights. It's a known issue.
Check fuse F36 in the rear SAM (fuse box). It's a 7.5 amp fuse that controls the door and trunk courtesy lights.
The rear fuse box is usually in the right-hand side of the trunk, behind a panel. Replace that specific fuse and your lights should work again.

Hi, thanks very much for your suggestion. In my case, it turned out to be the switch on the top console—I had accidentally turned it off without realizing what it did. A member on another MB forum kindly explained it to me. Silly mistake on my part! Thank you again for your involvment.
