Hey, here is the scenario: 1998 c280 mercedes. All of a sudden, the wiper blades, the directionals, the trunk and the windows wont wont. The drivers side window will go down manually. The trunk wont open manually or with the lever. I was told to replace the k40 relay. I did that, no results. any ideas?? I could really use some help.

 

Replace the K40? Can't think why you were advised to do this.

Have you checked your fuses with a multi meter rather than just visual?

Strange mix of non functioning systems.
