1995 C220 Speedometer
I believe that the Speedo signal comes from the left front wheel speed sensor and that may need to be changed. There are also a couple of fuses you should check for the insterment cluster.
Also, for some odd reason they decided to send the same wire to the back of the radio, and its possible that if your radio doesn't work that it could cause the speedo to also not work.
just a few ideas.
I'm also having an intermittent problem with my speedo and have been looking into this lately and have yet to find the problem.
