The cable on my drivers door snapped Got the internal door panel off only to discover another panel (steel) bolted on. Undid all the bolts but could not remove it. Went to local Fiat dealer and friendly mechanic told me the window had to come out before the panel would come off. Also told me that you cannot just replace the cable, you have to buy a complete winder mechanism, called a regulator (£50). The mechanism is pop riveted on to the steel panel, so must be drilled out, 4 rivets, new assembly fitted and riveted on, window slid back in, all bolted up and finished. Total time 2hrs! No special tools required!
