I'm noticing that on the driver side of my window, it squeaks when it's raining out and right after it rains. When I lower the window it's squeaks, and feels like it's almost off track. When I put the window back up it's wet on the outside and there's marks on the window. It's just happening on the driver side. All my other windows are fine. My car is going in for my 20,000 mile service soon, I was wondering if anyone knows what might be causing this so that I can let the dealer know. Does anyone know if there is a TSB out for this? I drive a 2013 S. Thanks
