Question No Right Turn Signal Trailer Plug

First time with towing with this 2020 F250, come to find no power for Right turn at 7 way or 4 pin flat at bumper plug. Tail Lights and Signals on box work.
Is there some place to check were plug picks up power. I'm going to take spare down to get a better look.
Left turn works, Running Lights work. Check this with a test light & 7 way plug in tester.

Truck is 6 months old, Yea I know under warranty, I just want to look at the simple stuff before I waste time at the Dealer.

So I was able to take the wiring harness off the plug.
I figuring out how to take plug out of the bumper, slight bit of corrosion cleaned it up dielectric grease put it all back together everything’s working.
