Does anybody have a problem besides me where their passenger side window glass goes down but still hangs about an1/8 to a half inch out of the door? Is this normal or could my regulator be messing up? I have a 2004 RX8

 

It's your regulator. I have the same problem on my Mazda 6i. It will go down, but it won't go up. I had it checked, and surely, it's the regulator that is causing the problem. Good luck.
