I think anyway lol, I won this facelift climate unit for £23.50 delivered. eBay - The UK's Online Marketplace So options are: A - swap the whole unit, although I think this may cause problems as the AC button is different to the Econ button on the older style ones. B - Swap the twist knobs over onto my old unit. Anyone done this or have knowledge of whether the new one works plug and play? If not does anyone know how the twist knobs come off?
