Three out of four of the windows are stuck, luckely in the closed position. This seems to happen often with the Accent, still what is the cause and is there a not too difficult way to fix this myself? I wouldn't call myself clumsy, but I'm also no technician.
More on the car: 1995 Accent 5-door with manual winders, Dutch version (hence not named Accent, but Excel).
Any help would be appreciated.
