Wing window is usually pretty easy. Once the stainless frame is removed from the larger chromed frame, spread the corners of the stainless frame, the glass usually pulls out without too much trouble.
Door glass is more challenging. The lower frame has a couple screws at the back. Remove those and then use a block of wood to butt up against the bottom frame and tap it off with a rubber mallet. Same procedure with the stainless door glass frame. Have to be careful as it's easy to split the upper rear corner.
