I’ve got a 2018 Ford F150, 45000 miles, automatic, 4WD
When I turn the air conditioner on, it doesn’t come on and the 2H dash light blinks. Read a little about it being a grounding problem. I don’t believe it successfully shifts into 4WD either.

Well yes, pray it's just a grounding problem. Now. They're a ground wires all over the place. So what you do is get a wiring diagram of all the ground points and check them all to make sure the wires aren't corroded. The bolts aren't loose or there aren't any broken wires that rubbed and broke off
