I Need Help Plz !!!!

Hi, My Door Windows Just Will Not Open ....what Can I Do B4 Taking To The Mechanic....?
325 Is Coupe 1996

If you know how to open the interior cover, open it and check the motor by multiple meter.

If the sunroof is also inoperative, replace the Comfort Relay under and behind the instrument cluster. Remove the underdash cover and knee bolster for access to the small relay bracket up there.
