my car was left without a battery and through a 'start' I loaded the battery until I could start it.
The problem is that I now notice that electric windows do not work properly. Every time I squeeze the drop or climb button it works only for 1 second and then turn off, and I have to press it several times for the window to fall/climb completely.
You have to program the windows with the glass below you all give down with the switch and keep 3 seconds, the same with the glass above. In this way the crystals will download only with a switch pulsation.
