Hi there I have recently bought a ford KA 1.3 January 2008 model. The heater, when the car is warm, is constantly on hot, even when its off. I have googled this and it looks like it is most likely be the control valve. I have ordered one, would this be easy to fit? Have you a listing of mechanics who could do this for me - i live in CV9 North Warwickshire, thanks Jane also my cigarette lighter isnt working to charge up my phone or electronic cigarette,would that require a replacement unit and if so, how easy is that to fit.
