The one-touch auto up/down feature on the driver's door window did not work when I climbed into our G35 today. It went down fine, but I had to hold the switch to raise the glass. It reminded me of a little trick that saved us a trip to the dealer. It works for many of the one-touch windows on the market today...
In order to re-program the switch there are a few steps:
(1) Raise the window.
(2) When it's completely closed, hold the switch in the window-up position for 10 seconds.
(3) Lower the window.
(4) When it's completely open, hold the switch in the window-down position for 10 seconds.
(5) Repeat steps #1 and #2.
At this point the problem should be no more. Try it once or twice at a later time if the issue persists. If a second try still doesn't remedy the situation it may require dealer service after all.

Nice job re-initializing the window motor, Mike! BMWs have a similar re-initialization process.

Does this work on ALL vehicles or just some?

Thanks for the info, I was excited to be able to fix my 08 G35's window issue .. BUT I tried this, and my window got stuck and I had to "help" it back up (with several button pulls while tugging up on the glass).
I am going to let it "rest" a while and try again maybe, I dont know what else to do. I guess I will be forced to go to the dealer if it doesn't resolve itself. : (

I'm late to the party, but I wanted to thank you for posting this. My '08 G35 was having this exact issue, and you just saved me a trip to the dealer.

Thanks for this awesome information. I replaced the battery on my 08 G35 Sedan. When I started it up the auto up feature no longer worked. This fixed the problem. I did the driver window first and like gixxer600 it got stuck in the down position. I pulled on it and used the button but couldn't get it to go up. Frustrated I turned the car off and let it sit for 30 minutes. After that I guess it reset because it went back up with the button (still no auto feature). I then tried the instructions on the front passenger window and it worked. I did each of the other windows finishing with the driver window and it worked perfectly on all of them. Thanks so much!
