I have a 2006 Lexus IS250 AWD. Just recently while driving I will hear some noises. Its not so much rattling but sounds like the windows are clicking/moving. The sound is muffled (still apperent though) if I slide close the moon roof door. I not sure if the moonroof glass part is loose and the window is moving around or a different window is, or what is going on. Anyone had a similar issue or know what could be going on? Thank you!
