Re: gt windows
The windows on the GT are designed to drop down a short distance when you open the door, then go back up again when you close them. They also have a function whereby holding the button for a short while will activate the window to either go down completely or come up. Sometimes this doesn't work, for a variety of reasons, and some owners have reported incidences of windows mysteriously opening themselves when the car has been left unattended.
Like all the electrics in the GT, the window system is multiplex wired and relies on many sensors and a central control unit to tie everything together. When this gets confused, it is possible to do a soft reset it in the following manner.
Lower both windows at the same time, holding the buttons down for ten seconds after they've reached the bottom. Raise them both together, again holding the buttons in place for ten seconds after they've fully closed. This should sort the problem, but it may come back. The definitive solution seems to be a software update to version 15, which would obviously have to be done by a main dealer. Apparently version 14 is still buggy, so insist on version 15 or higher.
