First of all I am not crazy . My rear passenger window from time to time will roll itself down about a quarter or more. I noticed it the first time after washing my car I noticed that the interior of my car was wet in the back. I looked around and saw that the water was coming in from my window that was rolled down partially. I thought maybe my daughter rolled it down. So for the next couple of days when getting in or out of my car I would look at that window and sure enough about 3 days later when I go to get into my car that window is rolled down about a quarter of an inch and those past couple days there has been no on in the car but me! From time to time when I get into my car I will press the window button to see if that window rolls up and sure enough it does! Anyone ever had this issue? Could it be the window motor?

 

BTW my car is an 02 TL typeS

 

could be motor or screw mechanism loose, or loose bolts to glass..??
pull the panel off and find out what it needs!

if not a DIY person find a glass shop that also does used glass, often near picknpull type junkyards/ now called auto dismanter and recycling

Those guys are experienced with door panels, know how to fix problems fast/cheap
and can often locate a used part for les$ if needed

 

I forgot to mention that I rolled window down, grabbed top of window and pulled and shook window to see if it was loose and it was not. So I doubt that the bolt to the glass is loose.

 

Sounds like you have a bad window regulator/motor.
