I rolled my passenger side window down and as soon as i let go of the switch it automatically goes all the way back up... i attempted holding the switch down for 15 sec and holding it up for 15 sec but its still doing the same thing... anyone ever had this problem before?

 

My '12 G37s coupe does that occasionally, I have yet to identify a reason for it doing that. I would be interested in knowing why they sometimes do that.

To clarify, it usually happens when I jab the automatic "down" button on the window. The window will go down about halfway, then return to the up position.
