Interior Condensation / Fogging Up

[Byrds8]

Mine has a sunroof but I have plans to tint it to help keep the heat out before next summer.

My '19 Colorado doesn't do this — just the '24 Silverado. That's why I thought it was odd.

Funny you grew up in LO, where are ya now?

Nearly twenty years in Montana, followed by a short stint back in Portland, and now across the river in Vancouver.

I picked up a '24 Silverado ZR2 Bison the other week. I noticed that if I don't have the A/C running full time, my truck's windows will fog up. I live in the PNW where rain, humidity, and condensation are persistent this time of year. But I have several other new vehicles from other OEMs, and this isn't a problem with any of those rigs. I can drive my '23 Super Duty in the pouring rain without needing to turn on the A/C. But my ZR2 fogs up immediately without the A/C on.

I noticed that there is some water that runs down the door panel. It's not raining today, so I wasn't able to capture the condensation trail. I'll circle back tomorrow when it's raining again. In the meantime, I marked in red in the picture below where I see water running.

I took it back into my dealer. They put it under their sprayer and said they couldn't find any leaks. They also said that condensation I am seeing is normal. And they said all Silverados do this. I am not sure I believe them.

Are any of you guys having issues with condensation, moisture build up, or fogging windows? If it is a design flaw, I can look past it. But if my truck is uniquely flawed, I want to know so I can lean on them to remedy it.

Thanks!

Yep same on mine
