why is my window screaching?

[fiveohpatrol]

my drivers side window is making a really annoying and kinda loud screach when it goes down or up, it seems to be worse the colder it is outside

it kinda sounds like metal scraping glass but i dont see any scratches (i guess it could be scratching the lower part of the window that you dont see)

is this possible? or is it more likely to be part of the scissor arm assembly thing?

im basically asking if this is a common problem and whats the best way to fix it?

thanks everyone
