Hello, I have a 2011 G37s coupe. Today I unplugged my battery and suddenly my cruise control doesn't work, and my windows don't roll back up automatically. When I turn on the cruise control, the cruise light comes on but when I try to set it, it doesn't set. The set light doesn't come on at all. Also about my window, in order to roll up my window all the way, I have to hold on to the buttons the entire time. They roll down fine though. One more thing. You know when you open the doors the windows roll down a little and they come back up when you close the doors? Mine doesn't come back up anymore. If I keep on opening and closing the doors, the windows will go all the way down.... Can anyone tell me what's wrong? Or would I have to go to the dealership?

 

You need to do the automatic window reset procedure, it is on the forum somewhere and it is also in your car manual. As for the cruise control issues I do not know

 

as for the windows.

roll them down then roll them back up completely and hold the up switch for about 3 seconds. that should reset the windows.

Sorry can't help you with the cruise control thing

 

From the manual:

If the power window automatic function (closing only) does not operate properly, perform the following procedure to initialize the power window system.
1. Push the ignition switch to the ON position.
2. Close the door and hard top.
3. Open the window completely by operating the power window switch.
4. Pull the power window switch and hold it to close the window, and then hold the switch more than 3 seconds after the window is closed completely.
5. Release the power window switch. Operate the window by the automatic function to confirm the initialization is complete.
6. Perform steps 2 through 5 above for other windows

 

Did you plug the battery back in?
