Need help Can't figure this thing out
Without giving you a long story. My hazzards, turn signal, wipers, rear defroster and horn aren't working. The fuses are fine and not blown. Is there a relay or some sort of module that control these features? If so the location. Any help will be appreciated.

since most of those things are controlled by the combo switch on the steering column, that would be my first guess. or possibly the wiring going to that switch.
also, i have had a hazard switch go bad on other cars that would cause strange things to happen, i guess because it is hard wired (even with ignition off). as far as the rear def, that is prob unrelated.

My problem might be the SAM ECU. The circuit under the relay box. Took it apart and found water in it. If anyone know where I can find one, or if anyone is parting out their cars it would be greatly appreciated.

sorry i don't come here that often but i'm willing to bet that the problem is the main relay which is what you refered to in your last post. inside the engine fuse box. it's that black assembly that has a few small pull out relays on the top and bunch of wireing cliped into it on the bottom, its very easy to change i changed mine before and i used one off a 430 and my car is a 320 they all interchangable from 320 to 430 to 55 you just might see a few more relays on the top on yours or the others which depends on what options you have or the doner car had such as head light washers etc... the wiring on the bottom is identical on all of the w208s because even if your car didnt come with the options such as head light washers the wiring is there so all you have to do to add those options is plug the switch and the pump but all wirings are there and they are identical. home this helped.
