Hi. My 1993 Mercedes 300SD is having a speedometer/odometer malfuntion. The car has been working fine but when I started it yesterday, the ABS light did not go out. I then noticed the steering was harder like the power assist wasn't working. Then the speedometer and odometers stopped working. The analog fuel efficiiency meter also is not working. I checked the fuses but all or OK and I couln't find any fuses in the diagram that control any of these functions. Is there a relay separate from the fuse boxes that control these functions and if so, where would it be located?
Thanks. Rick

You are describing a malfunction that is usually caused by dirty battery cables, or as bad ground, recheck all of your connections and let me know.
