The window in my 2011 G37s Coupe goes up and itgoes down just fine. The problem is if I only pull up the drivers side window, it'll go all the way up then slide down to a 3/4 ways up position. The only way the window stays up is if I hold the button up until it's all the way up. I already did the reset by holding both down then both up then holding for 10 seconds and it didn't do the trick. Any help? Do I need a new window motor?

 

Here's a quick vid of the steps of the reset procedure, which I think you should try again:
Note it's only the "auto-up" that needs the reset. It's your "anti-pinch" protection that needs to relearn where the top of the window frame is. It thinks it's hitting an obstruction and backs the window down a bit. The reset should fix that.

 

Late reply, but thank you so much!
