Remove inside door handle, window winder and door card. From window closed open it slowly until you can see the bottom of the glass, which should have a horizontal metal bracket with a few bolts through it. A helping hand may be required to secure the top of the glass as you remove these bolts the window will be free from the winder mechanism. It may be possible to pull up and out of the door to the outside of the car.If though it is still too tight you may have to loosen the vertical window guide bolts usually 10 mm bolt heads nearest the door closer which will allow the window to slide up and out at an angle. Hope this helps, good luck
