‘06 Trailblazer suddenly went dark

Hey Guys and Gals….
New guy here, 06 Trailblazer LS
Hope to find info to keep it running, except….

it sat for a while due to my surgery. My son put in on a trickle charge, it’s started and ran fine. But the battery was draining over a few days. I jumped it and let it charge, turning off the headlights. After that it held and started fine. My daughter needed a loaner, drove it forty miles, parked it overnite, and it’s dead.AAA came to jump it, when they hook up not even the interior lights come on. Guy checked the battery, says it tests normal. No dash lights, dome lights, doesn’t crank, even when attempting to jump it. The vehicle just went dark.
Help, please

there are a lot of possibilities. Somebody with a multimeter needs to get in there to probe and inspect all the cables, fuses, relays, grounds,etc.

Yup. I was just hoping there was a commonly known problem with this vehicle that would give me some direction

Check the underhood electrical center and see if the 125 amp Megafuse is good. Also check the alternator to make sure it is putting out proper voltage to maintain the charge on the battery.
