Hello,
The most common cause for window not rolling down when openin or closing the door is that door control unit lost the end positions of the window.
Please try to re-syncronize the respective window.
It is done by closing the door. Then push the power window button to roll the window down in manual mode (1st catch of the button) and hold the button pressed after the window is fully open for at least 5 seconds. You should hear the click in the door, which indicates that new end position is learned.
Do the same for closed position position of the window.
Do this for the rear triangle window.
In most cases this solves the issue.
Regards,
Stan
