Location of Fuse Box in the Trunk? 07
I have an 07 W221. I've torn apart the trunk of my car and can't seem to find the rear fuse box. Anyone know the location/how to access it? I think I've blown a fuse for my Comand, (it seems there are a few different ones to check in the trunk for it). When I was recently installing my stereo integration kit I did test the power and ground wires first, they were showing correct output, but my guess is that they must've crossed and blown the fuse when I was putting things back as they have no power now. I really appreciate your help!

It's behind the panel behind the back seat....next to the rear accessory battery. To get to it, remove the screws holding the bottom trunk cover where you can attach the trunk net. This will allow you to pull that rear panel out (with a little bit of work) and have access to the fuse box. While you're in there, if you still have the original accessory battery, you might as well replace it with an H8 AGM battery.

This is 100% the way to do it. I opened it up from the trunk and then realized I couldnt actually take OUT the fuses. You pull down the armrest, open storage area, and then pop off the plastic cover at the bottom.
