The window felt stainless trim is attached to the window felt itself and is removed as one assembly. Depending upon the year model and body style dictates the window felt style. But they are basically all the same with variations in the attaching method.
For the style window felt that you have pictured, I have found that for me the easiest method of removing the felts is as follows:
1. Roll the door or quarter glass all the way up.
2. Remove the door panel which means removing the armrest pad and base and window crank handle.
3. You are now able to reach your hand up into the door cavity. Running your fingers along the back side of the window felt area, you will feel the tangs of the window felt. Use a flat bladed screw driver, slightly bend these tangs back. Once all of them have been bent back, roll the glass back down. You should have enough room to rock the felts out and away from the body. Lift the felt up and that is all that there is to it.
4. To install new felts, roll the door or quarter glass down and simply align the correct felt to the panel and in case of this year model and body style, simply push the fingers of the clips back into the slots which holds the felt to the body.
I have attached a picture of a felt, it is not the exact style of yours, but for the sake of knowing what your looking at, will give you an ideal of the clip style.
