Whenever I roll down my windows and turn off my car, the windows roll up after a short while which is not what I want and it has never done this before until now.

Is there something i can do?

 

Usually it's the exact opposite. Folks roll the window up and it automatically goes back down. I suspect BCM failure but there is a switch in the door key lock (hold to locked position to roll up windows, unlocked position to roll down windows) that you should unplug to see if the problem corrects itself. Might be failing and making intermittent contact.

 

My 2007 G35S sedan windows (drivers and rear passenger) randomly began rolling down by themselves! Each rolls down while I'm driving, not necessarily simultaneously! Very rarely can I control/ stop the process. Just as rarely am I able to bring the window(s) up during that drive itself.
No specific pattern, but here are a couple things: often they roll down when it's super hot. Ive managed to reduce the frequency of them rolling down by shutting off/ pressing down the main window control button on the driver's side. Last week when it was 100°'s the rear window rolled down despite the main switch being off/ pressed down!
Help, I think I have a ghost in my machine!
