Running lights

[Mike Echo]

I own a 2014 GMC Sierra 1500 All Terrain. The running light don't work on either the 7 and 4 pin plus on my sierra. I ran a tester on both and confirmed. All the other lights work. Any advice on where to start with the issue?

When you say all the other lights work did you include tail lights? There is no separate wire for running lights. If indeed the taillights are also non working then you need to look at the fuse/relay box under the hood.

I agree, go through your fuses
