Today I was driving around in my 1999 C5 coupe and all of a sudden I noticed the speedometer was switching back and forth from MPH to KM/H. It did it for the rest of the day at times switching back and forth without delay then at times staying in KM/H for a while and then switching back to MPH for a while. I noticed the MPH and KM/H light on the speedo would dim a little before it would switch on it's own. Car is running perfect. No other issues. The speedo also would adjust to compensate from MPH to KM/H. No idea even where to begin. HELP!!!

Any help with this would be greatly appreciated. I have already replaced the E/M switch on the dash. ANy other ideas?
