which windows are you trying to remove?
the windshield has a locking strip in the center of the rubber on the out side,,, so does the rear window,,,but if they have never been removed,,you will have to probably slice the rubber gasket so u dont crack the glass
as for the door glass,, remove the interior door handles,,arm rest,,door panel,,and you will see how the door glass comes out of the doors,,,dont break the door glass cause i just threw away a hole set,,,
