I am having a problem with my speedometer, it doesn't work. Sometimes it moves sometimes it doesn't. My tach works just fine, same with everything else. its just the speedometer. It had the same problem before i swapped motor. So im guessiing its not the speed sensor. Maybe it may be the cluster. What do you guys think? Help please.

 

could be the cluster. take it off and look for broken / loose wires on the back somewhere.
