Rear parking lights, marker lights and license plate lights not working

My vehicle listed above quad cab, I recently noticed that my rear parking lights, and licenses plate, as well as front side marker, is not illuminating, however signal lights works, hazard lights works, backing up lights works, brake light works, headlights low beam and high beam works, interior light and dimmer and cargo light they all working. Curiosity checked bulbs noticed I have a couple of burnt bulbs and some half-burnt bulb so I decided to replace every bad bulb with a same exact number that was mentioned in the truck manual. Kind of expensive little things and meanwhile that I was replacing the bulbs I made sure to use fresh bulbs on all both sides land checked the lamp sockets corrosion and damaged free, no damaged wires so I checked all passenger compartment and under hood powerhouse fuses and relays reseated all no problem was seen. Then checked into the ground of chaise and everything was in order therefore I road-tested it and tried the lighting, not a change same issues as before, so I changed the cabin light switch now I thought that must be it again, no cigars!
At this point not sure what else could be wrong with a broken power wire somewhere or something else I mean after being on road for 44 years I thought this is going to be if not easy may be challenging but this is getting puzzling and spend the entire last Friday and Saturday on resolving it. I am baffled and stumped maybe you can give some magic insight to resolve the problem once for all.
Thank you

There is a separate fuse for the parking lights as well as a relay. I attached a pic below. Check to make sure there is power to the fuse and out. Also, check to see if the relay is good and has a good connection.

Note: The relay and fuse are in the junction box at the left end of the dash. See pic 2 for the location.

Here are a couple of links you may find helpful:

Make sure to check for power at the fuse.

Let me know what you find.
