Hi there I've joined here because my dad's having some problems with his mercedes s320 CDI. The problem had started from having it sat for a while he had a few electrical malfunctions but managed to fix the majority.

hes now at a dead end he currently has no power to his passenger seat controls no electric seat, mirror, windows etcs but had a current going to the drivers seat but he still can't control any of them. He's had star on it and the guy can control the drivers seat with that but nothing else.

The fuses f13 and f39 currently have no power going to them for some reason so this seems to be the problem but we can't figure out why because every other fuse has power ? He's replaced the Sam unit with still no luck can anyone please help I hope it all makes sense
