2014 GMC Sierra 1500 auto light problem

[Adam Holcomb]

Couple days ago I started having the left turn signal failure on the taillight. Bulb works and everything while braking and when lights are on. Wasn’t gonna worry about it cause it still works but then today my automatic light control was turning my night time lights on and off throughout the duration of the drive. No the sensor on the dash is not covered, it just turns on and off about 20 minutes each time. Bringing it into the body shop in a couple weeks. Askin if anyone has had this problem before maybe I can look into before I drop it off.

Welcome to the site.

 

Thinking this may be your problem, early K2's had a problem with them.
