I am new to this g37. The passenger window rolls down about 1/2 an inch when you open the door. However it doesn’t go back up. I have to turn the car on and roll up the window.

is this and easy fix, software reset, etc? Or something that is a bigger fix?

 

Looks like a window reset might do it? I read it in a post here: https://www.myg37.com/forums/body-in...matically.html

 

Great info. Thanks for your help.

 

Yep, happens after battery disconnect - need to roll it down, then up, and hold it up for a few seconds.
What's funny is that if you don't do the re-learn, the window will keep inching down as you open / close the door, so after a few times it's half way down, but won't go back up on its own.
