Good morning all.

New to the forum, but have learned a lot so far!

Bought a 2023 Yukon Denali a couple months ago, and now that the days are getting shorter, I've noticed that the driver's side running board light doesn't work. (It's just the LED strip on the bottom that doesn't work, the running boards themselves deploy and stow properly). I did find the other threads about the settings controlling when it comes on (locator light toggle and exit illumination duration) and was able to confirm that the passenger side running board and the backup lights come on when the feature says they should.

I did a quick check underneath and the wiring harness looks to be connected and undamaged. (I'm referring to the black/red wire bundle that goes into the front of the running board itself and runs to the larger connector near the motor.) The bumper to bumper warranty is already expired, so I'm a little afraid of what the dealer is going to tell me is wrong with it. Is there anything else quick/simple I could check?

I looked at the fuse descriptions but just saw some non-descript "exterior lighting module 1, 2, 3, 7, etc." so I'm not sure if any of those only control the light or if the light is part of the larger running board system. No fuses look to be blown, though.

Thanks,
Chris

Welcome to the forum from SW Ohio. I shopped Jake Sweeney before I bought my 2019 from Columbia Chevrolet.
