2016 Sierra SLT Front Left Turn Signal

[Moe Loller]

Left Front turn LED turn signal only works when the headlights or fog lights are on.    The amber LED on the left does not light up when lock or unlock button is hit on the key fob.  I have asked at the dealer and they had no clue what it could be without tearing into it.   This turn signal is sealed inside the headlight so I am not looking forward to having to replace the whole headlight assembly.   For now I just turn on my fog lights while I am driving so that the signal works.    Any thoughts or has anyone seen this before.

Unfortunately if the LED part of the headlamp is out, You will have to replace the whole assembly. I priced one the other day and it was around $1300.00 for a GM headlamp assembly for these vehicles. I Have not been on the inside of one of these yet, because if you disassemble the headlamp assembly they will not take the core back and that is $300.

 

Could just buy a aftermarket set. But they are never as good as OEM. https://amzn.to/2BQSEvm But for the cost you can buy 4 sets by the time you buy one GM headlamp.
