When changing the window regulator, it is important to be able to identify the different functions present on the original window regulator.
When an obstacle blocks the travel of the window, the anti-pinch safety function prevents a pinch force of more than 100 N being applied to the obstacle. This also applies for sequential controls and sustained pressure controls.
Regardless of the cause of failure (wear or incident), the window regulator has become a technical part that must be replaced at the very first signs of malfunction or noise.
