2021 Yukon AT4 with 16k miles. Self-installed GM's GMC black illuminated grill emblem on Day 1. Everything has been fine until today.
Walked out to my truck and noticed the driver side DRL was on. Car had been parked/off for hours, not remote started. Started it, drove it, parked, off/locked. Left side DLR still remained on and stays on for hours/forever.
Did a quick google and sounds like there may be a TSB about water infiltration on the lighted grill emblem, or power connector, leading to these results. However, I can't find the TSB or info on how to correct other than to unplug the emblem... which I can try, but it's also dark, cold, and wet outside. I'll try that, but trying to get more info. Not sure the dealer will cover if it is the emblem since I installed it.
Does anyone have an experience or a copy of the TSB I can review? My truck has been in the dealer service dept for past 2 months for lifters and fuel pump control module... trying to avoid another week without my truck.
Thanks.
