Hi, I disconnected the rear battery on my SL55 and now it is like the car has had a 'stroke', almost nothing works on the LHS of the car, windows, seats, mirror etc....help or advice from anyone please

Maybe the seat controller fuse has blown - it's #9 on the left fuse panel under the hood.

Have taken a look and F9 is fine, it is literally everything on the left hand side of the car that has stopped working, front and rear window, seat heating, movement etc....all on the RHS works fine......all was fine until I had to disconnect the rear battery???

I would measure voltage supply to the fuse. If you have 12 volts to it and the other fuses in that box with the key on, then the attached Signal Acquisition Module (SAM) is suspect. Otherwise the 200-amp prefuse which sources power to that fusebox and SAM are suspect. The prefuse is located in the passenger-side footwell of a LHD car.

Thanks will take a look, this did happen before and seemed to fix itself....very weird
