I have a 2003 Z. My windows started rolling up by themselves when I turn the car off. I have seen lots of threads about the windows rolling down but not about the windows rolling up by themselves. Is this the same issue? Do I need to reset the window motors? Has anyone else experienced this issue?

 

Mind you, this is just an educated guess, but it sounds like your BCM is getting a signal to roll the windows up due to a short in the key cylinder lock switch on the driver's side door handle. From outside the car, try raising and lowering the window by turning and holding your key in the door lock a few times and see if the problem goes away (at least temporarily). That could indicate a bad switch in the lock mechanism or possibly a bad BCM.
