Trailer Lights not working
I have a new to me 2014 F150 with a tow package and have a question regarding some trailer lights. The right side stop and turn signal lights are not working. I know its not the trailer because it is the same issue with two different trailers, and those same lights work on a different truck.
I checked the relay in the fuse box, traded it with the one from the left side stop/signal relay and it did not work. Put the right side relay in for the left to confirm if it was the relay or not. The left side still worked.
I still have parking/running lights on the right side. They still flash when I hit the key lock, they just dont work with brakes and signal. Any ideas?

The only thing I can come up with is fuse #73 under the hood, but that should kill both sides if it's blown. Check for a damaged pin in the truck socket, and/or maybe a broken wire at the back of the plug.
