Just recently, whenever I lower or raise my windows I hear a squeaking noise with each window but not all the time. It has been colder than usual lately with a lot of heavy rain. Could it be the rubber around the window or inside the door panel or both or neither?

 

I get a similar noise. There's a wear mark on a bit of rubber where the window disappears. I think it may have something to do with the squeak.

 

^My rear windows, that is.
