After the dealer replaced my drivers door window regulator, my window started squeaking really bad. So instead of dealing with them again, i got the service manual and found the window adjustment instructions and found it was way off. One quick check for you to do is look at the space between the door window and the rear side window {where the seal is}. There should be a even space between them about 9mm or 1/4 inch. And the top of the door the window shouldn't touch the top rain seal lip when the door is shutting.
