Well, have the same problem every season on the passenger side, because the battery is off over winter time.
In my Box it takes longer than 2 secs (manual says 5 secs). So i fully run the window down and let the knob pressed down for 10 secs. Than i fully run the window up and let the knob pressed for 10 secs. Than in general the one touch function is back. If not, i'll give a second try. Always got it back working.
