But this would have me going over the vehicle electrical connections. I'm not writing this is it but it's the FREE procedure I want to see if it helps. I start at the fuse box and using the fuse puller tool and be sure I can see what's what with good lighting I pull one fuse at a time and put it back into the same spot. That done I wait and see if that helped. If not I try other electrical plugs and do same. If a plug is stubborn I don't press my luck.

It's most likely a poor connection. But where?
