Scottco Posted October 7, 2023 Share Posted October 7, 2023 (edited) My dash cluster randomly blacks out. Nothing works at all. It will randomly come on and be fine a few hours or days then back off again. dealer said bad cluster, i bought another one to the tune of $1500 and it’s doing the same garbage. anyone else seen this problem. I saw on here that older trucks had this problem. i have cleaned the data link plugs on the back- 3 of them Edited October 7, 2023 by Scottco Quote Link to comment https://www.bigmacktrucks.com/topic/73391-2012-cxu-613-instruments-cluster/ Share on other sites More sharing options...
Joey Mack Posted October 8, 2023 Share Posted October 8, 2023 Check all the gray wires above the throttle pedal. Remove the triangular fuse cover to get a good look at them.. and for fun... clean the gray wires outside on the firewall.. Those gray wires are the grounds... 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73391-2012-cxu-613-instruments-cluster/#findComment-539855 Share on other sites More sharing options...
