On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls. Pull back the weather seal and you should be able to see everything. Your regulator may be bad or the window's caught on somethign

I can't give you the play by play just in general.You got to find the hidden screws that hold the door panel on.(most likely under handles) there are sometimes hidden buttons that unsnap.I've seen the so called installers mess up on removals.After you get the door panel off ,remove the window glass held by glass clips epoxied in.Install glass put back on door panel.Electric windows get more complicated with tension / cables.My advise Man you got a Porsche bring it in get it done right.Good Luck.

if the window is off track the regulator is probably bad. to remove the door panel should be a couple of screws by the inside pull handle and possibly one by the door handle itself also check the bottom of the door for any then just pull it off and lift up to clear latches and remove plastic film to get to inside of the door

Well first take the mirror cover off. Then the roll up window handle if its manual. There is a star head behind the handle to open the door, remove that and unplug all wiring.Then behind the handle to close the door there is a cover, it has 2 screws, take those out and the rest is just plastic door clips just pull away from the door and they will start coming off.

You need to take the window crank off.  There should either be a screw/bolt going straight into the handle where it is attached to the door (there may be a cover over it) or a clip on the back of the handle.  If there is no screw pry the handle out gently and look between the handle and the door panel - take a small screwdriver and pop off the clip holding the handle on.
