My driver side window squeaks just before it finishes rolling all the way down and right when I begin to roll it back up. About half way up or down it stops. I cant find where it is rubbing, but it sounds like it is rubbing near the rear end of the weather stripping. Any ideas of how to stop it?

 

Just spray silicone spray along the runner. X

 

Wont that smudge up the window??
