Hello,
I recently bought a used 2016 G63 with lumbar support seats. The seats on the passenger and driver side work perfectly fine when moving up/down/forward and back.

The issue i have are with the lumbar adjustments. They seem to not work on both driver and passenger. This make me believe that a fuse is out which control them?
Has anyone had this issue? know where to locate the fuse box in the back near the spare tire/trunk?
The user manual guide suggests there is a fuse box near the spare tire, but since i am a newbie, i was hoping someone here could help?

Thank you,

Mine don't work, and everyone i've asked, theirs stopped working also, so I am very interested to see if anyone has a solution.

I strongly believe its the fuse that's out and can simply be replaced. Problem is locating the fuse box in the back, and since im not an car expert id have to refer to the dealer which would charge me a lot to fix this minor issue. I was hoping i could find some DYI on how to access and swap the fuse.

Thanks,

Best thing to do would be to remove the side panel on the side of the dash on the driver's side and look at the paper fuse diagram.

This info says the multi-contour seat fuse is located in the center fuse box, under the arm rest, accessed from the passenger side (you have to move the passenger seat all the way forward to remove the panel.

Fuse #13, 20amp fuse.
This link says it's a 5amp fuse

Here's info for fuse box locations on all W463's

A common failure point on all G's for the multi-contour seat is the air pump goes bad and the air bladders for the seats start falling apart. If after replacing the fuse your pump still does not run, then that will be the issue. It is located next to the battery on the rear passenger side floor.
