My driver's side front power window seems to be slipping or something. It operates normally for the majority of the window's range of movement, but at the last 1/8" or so, when the window is pushed in to be snugly closed, I hear a "rut-tut-tutting" noise as it closes firmly. Then, when I open the window, the noise immediately starts again and the window sometimes does not open unless I help push it down by hand.

If I do not fully close the window, it goes up and down smoothly.

I am thinking that perhaps something is slipping? Gears worn?

Any help would be gladly appreciated!
