Do the following with the windows down. Your first step would be in aligning the door height to the body by adjusting the hinges at the door. You will have to loosen the piece at the back of the door that the latch closes on to while you do this. Next adjust how far the door goes into the body at the latch. Your doors should now close easily with the windows down. Raise the windows to see if they still close properly. The tilt of the glass is adjusted by two set screws that you access by removing the lower cladding of the doors. They are behind two rubber plugs. If there is too much tilt in at the top your doors will be hard to close, if there is too little you will have wind whistles at speed. There is also some minimal adjustment available to the amount the window rises out of the doors by adjusting the clamps at the glass itself. You have to remove the door panels for this.
