I noticed since i bought my 2007 tl type s that when the window was rolled down half wat or at all, as i shut the door it would make a rattling noise. Ive concluded that the driver window inside the door panel is loose and it has some play in it when wiggle it a little. it also sometime makes a really loud snarling noise when rolled up from being completely rolled down. is there a way to "tighten" the window to reduce the play i have in it?

 

I'm currently having the same problem with my front passenger window. This started about a year and a half ago (original owner of 2004 TL/158,000 miles). The noise it makes when I 'Auto Roll' the window back up is really loud now. I believe this problem could be related to the window regulator.

 

tl windows when rolled down part way will rattle when closed. everything is tight inside of the door its just the actuator design.
