I have a 2015 Silverado 2500HD...
I'm getting that same message on my screen (Action Required Open Then Close Drivers Window)...except neither window on the drivers side will go down, and the radio won't shut off after I pull out the key.
I've been having trouble with the 'Door Ajar' alarm on the back door drivers side and I'd jiggle the wire harness on the back door and it would make it go off...plus when this would happen the electric door locks quit working until I jiggled that wire harness.
However, just before the windows quit, the 'Door Ajar' warning went off for both drives side doors and I couldn't get them to go off...then suddenly they did, and this is when this window alarm started going off.
Anyone have any ideas about this issue?
