Passenger rear windows half opening
 

Hi everyone, just curious to know if someone else have this problem: I'm driving a 2018 Chevy Silverado 1500, Crew Cab, 4WD. I have notice that, in a few occasions, I found the passenger rear windows half open in the morning. I thought that it was the remote starter, but I have the Remote Starter Windows option disconnected on Settings and this option, if activated, will open all windows, not just the passenger rear windows. I was wondering if it is related with the swinging weather (overnight with minus something, day with plus something), Any idea or someone that experienced this? Any help will be very appreciated.

Thanks
