Lots of good information in this thread lol. Maybe this will help get the ball rolling. I took a picture of the only plug I can see going into my headlights (2020 Trail Boss LT). Does yours look the same? I’m stuck here trying to figure out which wire to tap into for my SS3 fog light backlighting feature. Instructions show no picture but says tap into the side marker lights… everything is sealed in the headlamp though.

I can’t tell if you’re joking or just can’t hear your engine well enough, but either way thanks for the laugh.

GM has a new service bulletin haha! Their certified technicians are just going to advise customers to not drive or park in the rain.

Same problem here on my 2020 6.2L Trail Boss… still no fix?

I’m glad to hear there’s a fix. Thanks for sharing. I’m looking at a few options with UCAs.

Those are all the top quality GM parts just bumping and grinding together in harmony… it’s ****ing beautiful

Mine took a year and a half until it showed up… just a few drops.

This is exactly the same thing my 2020 LT Trail Boss does (power sliding window). I’m not even sure it’s worth the trouble of having everything ripped apart by the service monkeys at the dealership.

This just happened to my 2020 6.2L Trail Boss. Truck threw all those codes while driving, so I pulled over parked and shut her down. Then I tried to restart the truck and it wouldn’t start. About 20min later it finally started.

I bet your dealership sold you a problem truck that someone else dumped out of frustration. Then the sales staff slapped a “dealer certified” banner in the window and called it a day.

Mine is still doing this too (in addition to periodically not starting and throwing a ton dash codes and alerts)… no fix from the dealership of course.

Christmas will be here soon enough, so let’s all just sit back, enjoy some eggnog and let the jingling bring about the Christmas spirit haha!

Just wait another 2 years and eventually you’ll get an answer on here
