I'm getting a very loud screeching sound coming from my drivers side window whenever I try to lower the window. -Its similar to scratching a black board with nails.

At first I thought it was because of my tint, but I had the tint removed and it kept making the noise. The dealer replaced the little motor for the window, and gave me a new window track which fixed the problem....

but as soon as I saw it fixed I decided to put the tint back and once again its making the screech noise when it goes down, but no noise on its way up.... Any help would be appreciated...
