So I just had to replace my 08 g37s battery. After replacement however, every time I turn the car off and open the doors, the window goes down on the door that is opening, after the car is already turned off. It does this for both the driver and passengers doors. When the car is on however, the windows on both sides operate fine. I've unhooked the battery and let it sit to "restart" the system a few times but the same issue occurs. Any advice on a fix, I'm sure it just needs a computer reset or something.

 

Press the window switch down all the way & hold for 5 seconds, then press it up all the way & hold for 5 seconds...this should reset them. Will have to do each switch from the drivers side.

 

Worked perfectly. Thanks for the quick response too!
