Trying to remove the passenger side window from a 1991 Buick, Regal to put into another 1991 Buick that is broke, but can't figure out how to remove the window. I have the door panel and trim removed but can't get the powered window out. Are there clips to push, do I need to have the power window partially rolled down? Thank you for any advice in solving my issue.

I honestly have never done one so i wouldnt know but their are two or three types of fitting here ,one is where the window has to be down a bit as it has a clamp on either side which normally has a 10mm size nut ,then their is another tupe which has one fitting in the middle with window half way down you put yoiur hand behind the glass and twist a square piece of plastic which then comes off so the peg can be pulled or it will have a horseshoe type clip that you slide off .
