we just replaced the window/sunroof controller under the drivers seat

the original part number on the car is: 928 618 240 00 the replacement part from Porsche is: 928 618 040 00

When the replacement part was installed the driver window switch when pressed now controls both the driver widow and the sunroof

When the sunroof switch is pressed it does the same as the driver window switch - operates both the driver window and sunroof

Thus the driver window and the sunroof cannot be operated independently

The passenger window switch operates normally

is there a solution to this problem in the wiring and/or pins on the connectors to the controller?
