Right rear running light and right licence plate

Right rear running light and right license plate light have no power.
Brake light ,turn signal and backup lights work. Can't find any damage to wire harness. Could it be multi function switch?

 

Looks like it piggybacks off the left taillight so your problem would have to be either in the left taillight or the wire between them.

Thanks to all. Dm93 thanks. I guess tomorrow's project is pulling the tail lights out and checking the plugs and harness....wooohooo!!

 

Shouldn't be much to check, see if there's power coming out on Pin 6 (Green) of the left tail light. If there is then the wire is broken between the left and right tail light, if there isn't then there's a problem in the left tail light.
