I just got my Z a few days ago. I love it, but I'm still trying to figure all the little stuff on the out car. So whats up with the driver side window. I turn offf the car and close the door and the window comes partially down. Is that normal operation or what. Also some times I want to roll it up and it goes all the way up and then comes right back down halfway. Is that some kind of setting or do I need to take it to the dealer and start using my waranty. Will someone break it down for me. Thanx
