Mackpro Posted December 9, 2013 Share Posted December 9, 2013 Is it a GU model ( I assume it is)? Here is the only Mack bulletin on the dash cluster but it wont help much. Id say either the cluster is bad or the data lines from the VECU to the cluster are bad. Check fuse to the dash cluster first.cluster.pdf Quote Link to comment Share on other sites More sharing options...
Mackpro Posted December 9, 2013 Share Posted December 9, 2013 There was a recall on some dashes, see if yours falls under this build date. Sadly the recall is expired.cluster 2.pdf Quote Link to comment Share on other sites More sharing options...
