I have a 2000 Ram 3500 5.9 cummins, 6 speed manual and have a blank display in the overhead council. It worked fine, with the exception of the lie o meter, then one day it went blank. It has come on a couple of times since but now is totally blank all the time. Any suggestions on what to look for and try?

Thank you,

David
