Hello.
Ask for some help or advice. So the problem is as follows. I have CLK 270CDI 2003. I decided to make a change on the center console with the facelift one. I have a panel with buttons for ESP, hazards, locking, etc.The part number i 203 821 49 81, and i believe this is identical for all facelifted models. Yesterday I decided to try the new panel if it works by him alone in the car. As far as I was reading the differences are within the socket, but the wiring (4 wires, two of them are woven into each other, brown and brown / red for CANBUS and two wires for power) are identical before and after the facelift. I jack of the facelifted panel with cables, so I decided to connect them to my car to try. Unfortunately it did not work, none of the buttons working. The problem is that i got the SRS error on the dash, and after i put my original panel back, the buttons no longer worked. Also, the control panel of the air conditioner died. Completely! Nothing works. Even backlighting does not work. And my radiator fan turns itself at maximum speed as soon as I start the engine. My question is where to look at for the problem? Could be a fuse somewhere blown? Or I fried a sam module? Could be just the software error from changing the upper control panel and clearing it solve the problem? I want to check at least basic things first, before i go to the service.
