GMC Mechanic: Pete, GMC Mechanic replied 1 year ago
O.k.,there was a common fault with this issue here with the electronic ignition switch failing intermittently failing to send power signals on one or more of its circuits causing this issue.Locate the gauge fuse and the trans fuse and when this issue occurs test and see if these two fuses have battery voltage on at least one terminal the fuse plugs into while the issue is occuring.If there is no voltage this indicates the electronic ignition switch needs replaced.I have had to replace quite a few of these before for this fault here. If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.Thanks Pete
