2015 Sierra light problem

[Kroos Kontrol]

Been having this problem for awhile now, and can’t figure out what is going on. And having seen anything online to fix it, which is surprising.... I decided to join the forum, and ask...because being from Texas, I’ve actually seen many trucks with this sort of problem. Both Silverado’s and Sierra’s, used to think their lights had gone... but now that I’m experiencing it with my own truck, guess that wasn’t the case. 
 

so here’s the problem: some times, not all the times... Running lights only turn on on the left side(driver side)....but nothing on the right side. Including the back taillight. Everything, absolutely everything else works(headlight, the longer headlight, turn signals, break, everything)... but not the running light. And whenever this occurs, it does the same with the tail light not staying on, like it’s suppose to. Anyone have an idea what it can be?...

Welcome to the site, this may help.

^ thanks. And yes, had seen that vid. Unfortunately it wasn’t that.  

 

like I said, not sure what is up, but both the front light and the taillight on the same side, do the same thing, at the same time. 
 

Anyone know if maybe they share some fuse or wire?
