Peugeot 207 observed a typical failure in the work of the driver's door window: the glass is not closed for the first time.
In this case, it is necessary to conduct "training" or initialization of the window-lift. This requires:
1. Hold the button and lift the glass up.
2. Once closed, press the button again and hold it for 1 second;
3. Delete the glass by pushing the button 1 times (the glazing shall automatically be lowered to the point of emphasis);
4. After opening, click and hold button again for 1 sec.
The window-lift should then operate normally. Other failures, for example, if the window-lift responds to the button, can be caused by the oxidation of the contact on the control button board. In this case, it is necessary to remove the oxide, with a soft cloth with a small amount of alcohol.
