If they are broken, what is there to remove besides the glass with a vacuum?
If the regulator is not working, take the door panel off by removing the 2 plastic caps covering the 2 screws under the door pull handle, and remove the screws. Remove the window/lock switch and disconnect, pry up on the rear end I believe. Pull off the door panel from its fasteners, disconnect the small speaker from its connector if you have the BOSE sound, you cannot pry its cover off, it will break. Remove the panel from around the door open lever. The panel fasteners are not the greatest and you may break a few doing this too.
Pull back the clear plastic vapor barrior and then you will have access to all the regulator botls and window.
I am not sure though on what you are exactly doing, replacing the windows, regulator, or motors?
