sqealing window

[slimnottygirl]

02 trailblazer, I just replaced the power window switch on the drivers side window as it wasnt working, it worked great for approx 2 weeks and now all of a sudden when i put the window up it is sqealing really loud like something is rubbing on it, I cannot see anything that would be making sounds but really need for this noise to go away as it is really annoying anyone got any ideas?
