I have a pretty new 05 TL. (4 weeks/1500 miles) Yesterday was the first day that I rolled down the windows when it was raining. When the windows went down they stuttered and stuck on their way down. I'm assuming it's because the windows are brand new?

 

I had a similar problem with one of my windows. I took it to the dealer and they lubed the window.

 

My 04 non-navi 5AT did the same thing. I took it back, the dealer claimed it was due to faulty weatherstripping, and replaced it, but that didn't help at all. Traded it in for an 05 navi, so I dunno what will fix it. Sorry
