I don't think you can do just one at a time. I know i can only get all of them down at once and i've heard thats all that can be done, but i could be wrong. On a side note maybe someone knows, when i picked up my car i can swear the guy got all the windows to close when he locked the car. I can't seem to do that now any one know if thats true and how you have to press the button to do this?
Thanks
