Mine has wiggle room when I pull up on the window switch. Like the window as a mm or so wiggle room. Is that what you mean?mine was fixed when they replaced the window regulator, A good way to test to see if its causing this is to sit in the car with the all the windows up. Then in silence, pull up on the window switch and all of them should have a similar sound except that 1 window that rattles, it will sound like the glass is hitting the top. Thats how you can show the service to come fix it.
