A207 fuse location for roof
My hydraulic pump stopped working suddenly. I can only follow along with C-class videos/info, which are similar. They have a 40A fuse in the trunk, about a foot away from the pump. My E-400 has no fuse there, power wires seem to run up and under the rear seat. Does anyone know where the fuse for the hydraulic pump is located? I've had zero luck at the dealer (bring it in) [I just want to check the fuse] ( bring it in) [screw off, I'll find it]. Hopefully one of you guys can help. I believe the power wires are green, with brown stripe and pink stripe.

I traced the power wires to a module [p/n A207 900 65 00 (04)], located behind the passenger side rear seat in the trunk. It's near the trunk mounted (spare tire) fuse box .
When attempting to put the roof down, nothing happens. Using the key fob, the window's go down, and that's it. Using the up button, there is a faint, 1-2 second hydraulic pump sound, and that's it.
The pump has been rebuilt, a replacement switch has been tried. I'm at a loss on what to check next, it would be nice to locate fuses.

Well, the repair was beyond my capabilities. Off she went to the local European car repair guy. He replaced a switch or two, not certain it was required. In the end, he gave the rear seat head-rests a downward punch, and the roof began to work. He found the cause, but wasn't able to do a repair. MB doesn't have a part number for the integrated headrest/windscreen switch, he feels they sell the entire thing as a unit. Let sleeping dogs lie, if it rears it's ugly head again, we'll try to fix it, until then, I'll enjoy top down driving.
