For a while now my window has been dropping by 2-3 cm since i tried opening the window on a frosty day.
I took the door skin off at the weekend and found the cable had snapped, and therefore the window function was f'ed.
Im looking to get this problem sorted, as summer is coming up and windows are a nice feature

.
What part(s) and part number(s) will i need to get the job done myself?
