sl 320 1996 - electric window
 

hi, the last 2 days when i open the door (left or right) the window goes down and stops in the middle. please advice

This is only a suggestion, but I had a similar problem and solved it by starting the car, open both windows fully, then close fully and hold in the buttons in the up position for a full five seconds. This resets the sensors which control the sealing of the top of the window against the frame when the doors open and close. Try this, might work!

thank you for your reply. it really worked

You're welcome, George. Those German engineers had plenty of tricks up their sleeves, and this is only one of them!
