Since I have owned my 2019 Blazer from new, I had a few random times that once I go out to my car or overnight and find all 4 windows fully open. Fast forward to this month, I now believe it happens when I may close the driver's door harder than usual, At this time, I had just gotten in my car and pulled the door harder than normal, and I was able to watch the window magic in motion!
I checked with my local dealership and of course my appointment is a cpl weeks out, but more important they claim they have not heard of this happening, but will have to take the door apart and go thru the electronics.
Has anyone had this happen? and if so, what was the solution?
