Ok after chasing the wires thru the dash, under the hood, we found a grey piece of flexible pipe holding several wires. It goes down to the fuse box in the basement under the driver seat. It holds stuff like the awning, solar power, seats, etc... The 2 DC Nd USB ports are called “power point”on the cover of the box. Sure enough the fuse was blown, changed it and they work fine. So there’s a fuse box under the dash inside, one under the hood, one in the basement, one under the frig. Lots of places for things to go wrong. Yippee!
Thanks for all the suggestions
