1997 Mercedes Benz C180

Electrical problem
1997 Mercedes Benz C180 4 cyl Two Wheel Drive Automatic

When driving the car, somtimes the fans work, but I cant open the windows. Sometimes one window opens and the others dont. Sometimes all the windows work but the fan doesnt, Sometimes when I try to use the key fob to enter the car or lock it, it only works after several attempts and only by the drivers door. I never seem to have everything working. I ve changed fuses, but this doesnt help to much. Help

This sounds like a control unit issue since the problem is in several areas of the vehicle. A software glitch within a Signal Acquisition module is more than likely the issue. Sometimes these control units can be updated, oter times the control unit will need to be replaced. I would recommend bringing this to the dealer since they will have the best diagnostic tools to address this issue.
