The HVAC controls are completely dark, no display, what now

ID Status Date Year Make Model Transmission Type A/C Controls Public/Private

Out running around town when I noticed the HVAC controls went dark, no display, checked all fuses that pertain to HVAC system all ok, did my HVAC unit die?

I am assuming you have auto controls and you are referring to the central display.  If you have checked all fuses related to the panel the next step would be to remove the control panel and check powers and grounds at the connector itself. If present the control panel died.

Yes auto controls, removed unit from car and took it apart, could not see any issues and reinstalled and now it works, maybe un plugging and plugging it back cleaned the contacts on plugs.
OK now I have no confidence it will keep working, I will use truck for a while and see what happens.
Thanks
