1983 300SD - Sometimes the speedometer works, sometimes it does not. It appears that I have an electronic speedometer because there is no cable. I removed the instrument cluster and sprayed all of the contacts with contact cleaner. No help. I searched this forum and could not find a similiar post. Any ideas?
