Customer Question

I have a 2007 sl55 that has electrical problems. The trunk latch won't open, the window does not open when opening the right door only ( left side works) the button on top of the seat on the left side does not operate (right does).
I brought to Mercedes and for $1200 they got some of the things to work for a couple of days. They said the fuse block behind the passengers seat got wet which caused the problems. They said they could fix it for $2500 by replacing the box or try cleaning the terminals. I see only two boxes there one the obvious fuse block and the other I would guess is a theft control because it says do not remove this box. Can you tell me what to replace and should I get the theft box?if I disconnect the theft device will it need to be programmed?

Hello. The fuse box in the rear is the control module. It's called a rear Sam. You can find them on eBay. Once replaced you will have to have it recoded for your vehicle. Hope this information helps.
